The exploding planet Krypton from History of the DC Universe #1 (1986)

Krypton, a planet in the DC Universe and the native world of Superman, is named after the element krypton, which is abundant in its atmosphere. Krypton is also the native world of Supergirl, Krypto the Superdog, and Power Girl (in her case, an alternate-universe version designated "Krypton-Two"). It has been consistently described as having been destroyed just after Superman's flight from the planet, although the exact details of its destruction vary by time period, writers, and franchise. Kryptonians were the dominant species on Krypton.

The planet was created by Jerry Siegel and Joe Shuster, and was first referred to in Action Comics #1 (June 1938). The planet made its first full appearance in Superman #1 (Summer 1939).


Krypton is usually portrayed in comics as having exploded as a result of a nuclear chain reaction caused by the planet's unstable radioactive core (which created Kryptonite, deadly to Superman). As originally depicted, all the civilizations and races of Krypton perished in the explosion, with one exception: the baby Kal-El who was placed in an escape rocket by his father, Jor-El, and sent to the planet Earth, where he grew up to become Superman.

In some versions of the Superman mythos, additional survivors were later discovered, such as Krypto the Superdog, Supergirl, her parents (kept alive in the "Survival Zone", a similar parallel "dimension" to the Phantom Zone), the criminal inhabitants of the Phantom Zone, Dev-Em, Beppo the Super-Monkey, the residents of the bottled city of Kandor, and the real parents of both Superman and Supergirl.

From the late 1980s through the early 2000s, the number of survivors was reduced to Superman himself in the comic book stories (the Eradicator was added in 1989 as a nonsentient device,[1] and shown to be self-aware in 1991[2]), but more recent accounts have restored Supergirl, Krypto, and Kandor and introduced another newly discovered survivor, Karsta Wor-Ul.

Kryptonian civilization's reported level of technological advancement has also varied. Some works, such as in Kevin J. Anderson's novel The Last Days of Krypton, describe it as a few centuries ahead of Earth, while others, such as the Superman film series and Man of Steel, describe it as thousands or even hundreds of thousands of years more advanced.

Versions of Krypton

The Golden Age Krypton


In its first appearance, Krypton was only depicted at the moment of its destruction. Soon, beginning in the Superman comic strip, Krypton was shown to have been a planet similar to Earth, only older by eons and possessed of all the beneficial progress that implied (though the downside was the hint that Krypton exploded due mainly to old age).

The debut of the Superman newspaper comic strip in 1939 delved into further details about Krypton, introducing the idea that all Kryptonians possessed a level of heightened physical abilities, including super-strength and super-speed. In the early comics' version of Krypton, Superman's parents were named "Jor-L" and "Lora" (changed to the more familiar "Jor-El" and "Lara" by the end of the 1940s).

The Golden Age Krypton would be revised into another form almost as soon as it was defined (see Krypton in Transition below), and very few stories were written about it. However, after the introduction of DC's multiverse in the 1960s, this version of Krypton was declared to be the Krypton of the Earth-Two universe (the native dimension of DC's Golden Age characters) and its Superman.

After the emergence of Earth-Two as a differentiated alternate universe within the DC Multiverse, Power Girl (Kara Zor-L) was introduced as Krypton-Two's alternate Supergirl in 1976. Unlike the Silver Age Supergirl, who grew to adolescence in Argo City before its destruction, which led to her parents sending her to Earth, Krypton-Two's Zor-L and Allura sent their Kara to Earth as an infant without the intermediate stage. Because Zor-L was not as conversant with advanced astrophysics as his brother Jor-L, Power Girl's journey took longer than that of her cousin Superman (Kal-L), and she arrived on Earth having grown to adolescence. It was later established that she was brought up by Earth Two's Superman and Lois Lane, a married couple on their world. Kal-L and Kara Zor-L were the only known survivors of Krypton-Two, unlike the Silver Age analogue. Earth Two's universe lacked its own Brainiac, so its Kandor was never abducted from Krypton Two before its destruction, nor did Kal-L have his own version of Krypto as an infant and toddler on this world. Presumably, Jor-L never discovered the Phantom Zone on Krypton-Two, nor was it therefore used to imprison Kryptonian criminals by exiling them to that extra-dimensional prison.

In the Golden Age, Superman was unaware initially of his true origins; in Superman #61, Superman discovered the existence of Krypton for the first time and learned of his Kryptonian heritage. He later encountered other survivors prior to Kara's arrival in the form of three criminals, U-Ban, Kizo, and Mala, who were exiled by Superman's father before Krypton's destruction.

Krypton in transition

Over the course of the 1940s and 1950s, various alterations and additions to the makeup of Krypton were made in the comics. Among them was an explanation of why the natives of Krypton perished if they had possessed superpowers on their native world (as was the case in the earliest versions of Krypton outlined above, although this only became a problem once Superman and by extension anyone from Krypton was portrayed as increasingly powerful, able to withstand nuclear explosions, contrasted with his original power level in which a bursting mortar shell could penetrate his skin).

Thus, it was explained by the early 1950s that Kryptonians were powerless on their own planet and would gain superpowers only within a lower gravity environment. This matched the correct theories being published that when man reaches the Moon (a lighter gravity environment) he will be able to lift great masses and leap great distances. In the early 1960s, added to this was the need to be exposed to the rays of a yellow sun (versus Krypton's red sun, which was older and cooler, or put out less energy) to gain super powers, with the yellow sun aspect soon gaining the much greater emphasis. Other changes to the concept of Krypton and its culture were introduced, many of which were stylistic.

Silver Age Krypton

By the late 1950s, Krypton played an increasing role in various Superman stories, with greater detail provided about Krypton's makeup.


Kryptonians made use of their advanced science to create a world where scientific inventions and research influenced much of daily life. Robots and computers were used for many tasks on Krypton, even for determining what career paths young Kryptonians would take as they grew up. Scientific and technological research were highly valued on Krypton, with the ruling body of Krypton named the "Science Council".

Several stories featured characters traveling back in time to visit Krypton before its destruction; one example is the 1960 story "Superman's Return to Krypton", in which Superman is swept back in time to Krypton some years before its destruction. Powerless, he spends some time on the planet, where he meets his future parents-to-be and falls in love with a Kryptonian actress named Lyla Lerrol. A Superman "imaginary story" entitled "What If Krypton Had Not Exploded?" (reprinted in the trade paperback edition The Greatest Superman Stories Ever Told) gave more insight into Krypton's society.

Superman's Kryptonian heritage was a frequent factor in Silver Age Superman comic storylines, as he was fully aware of his origins from an early age. Superman would use this knowledge for such tasks as constructing advanced Kryptonian technology or observing some of Krypton's traditions.


One of Krypton's moons, Wegthor, was accidentally destroyed by the Kryptonian scientist Jax-Ur, who was experimenting with a nuclear missile that was diverted from its intended destination. The disaster killed 500 inhabitants of the moon and Jax-Ur became the first and only criminal to be banished eternally to the Phantom Zone. This disaster also prompted the Science Council of Krypton to ban space flight completely.[3]


The Silver Age Superman was not alone in the survival of Krypton's destruction, being joined by his cousin Supergirl, the Phantom Zone criminals, Beppo the super-monkey, Krypto the Superdog, a juvenile delinquent named Dev-Em, the entire population of the city of Kandor, Supergirl's biological parents, and even Superman's biological parents (in hibernation on a space ship - Superboy #158, July 1969), When the planet exploded, one entire city of Krypton, Argo City, survived the cataclysm.

Argo City drifted through space on an asteroid-sized fragment of Krypton, which had been transformed into Kryptonite by the explosion. The super-advanced technology of its Kryptonian inhabitants allowed them to construct a life-sustaining dome and a lead shield that protected their city from the Kryptonite radiation of the asteroid. The protective shield was destroyed in a meteor storm, exposing the inhabitants to the deadly radiation.

The sole survivor of Argo City, Kara Zor-El, was sent to Earth by her scientist father to live with her cousin Kal-El, who had become known as Superman. Kara adjusted to her new life on Earth and became known as Supergirl. It was later discovered that Supergirl's parents had survived in the Survival Zone, a parallel dimension similar to the Phantom Zone, from which she released them. When the bottle city of Kandor was finally enlarged on a new planet, Supergirl's parents joined its inhabitants to live there.

In 1979, a mini-series titled World of Krypton was published,[4] providing a great amount of detail into Krypton's history just before its destruction, along with the life story of Jor-El himself. A three-issue miniseries entitled The Krypton Chronicles, published in 1981, tells of Superman researching his roots[5] when, as Clark Kent, he was assigned to write an article about Superman's family by an assignment editor impressed with the television miniseries Roots. To do so, he and Supergirl travel to Kandor, where they learn the history of the El family. In 1985, writer Alan Moore gave a somewhat darker glimpse into the world of Krypton in his story "For the Man Who Has Everything" (in Superman Annual #11), the premise being an elaborate dream of Superman's in which Krypton had not exploded and he'd grown to adulthood there. Background details are culled from other Krypton stories. This same story was retold in the animated series Justice League Unlimited in an episode by the same name, and several elements were used in the Supergirl series episode "For the Girl Who Has Everything".


Main article: Daxam

The people now known as Daxamites were originally Kryptonians who left their homeworld in order to explore the universe. (In post-Crisis on Infinite Earths continuity, the Eradicator, an artificial lifeform programmed to preserve all Kryptonian culture, altered the birthing matrices ("artificial wombs") that the explorers took with them so that all newborns would be fatally vulnerable to lead and other materials such as greenhouse gases and certain rocks.) Thus, if they persisted in their anti-Kryptonian wanderlust, they would all die from it. One Daxamite, Mon-El, was poisoned by lead and preserved in the Phantom Zone until a cure was found by Brainiac 5 in the 30th century, whereafter Mon-El became a member of the Legion of Super-Heroes.

Crisis on Infinite Earths

After the 1985 mini-series Crisis on Infinite Earths, the Silver Age version of Krypton was replaced by a newer version. The Silver Age Krypton made a rare post-Crisis appearance in The Sandman #48, during a flashback sequence featuring Death and Destruction of The Endless, beings who were unaffected by the reality-altering events of the Crisis.

Modern Krypton

The Man of Steel

Following Crisis on Infinite Earths, which rebooted the history of the DC Universe and retro-actively eliminated the existence of the Golden and Silver Age versions of Krypton, writer/artist John Byrne was given the task of recreating the entire Superman mythos. This rewrite was started in the 1986 Man of Steel miniseries, which addressed Krypton in both its opening and closing chapters.

Krypton itself was the main subject of the late 1980s The World of Krypton miniseries (not to be confused with the 1979 miniseries of the same name). This miniseries was written by Byrne and illustrated by Mike Mignola, and filled in much of Krypton's new history.


The new Krypton was approximately one-and-a-half times larger than the Earth and orbited a red sun called Rao fifty light-years from our solar system. Krypton's primordial era produced some of the most dangerous organisms in the universe. It was for this reason that 250,000 years ago, Krypton was chosen as the place to create Doomsday through forced evolution. Until its destruction, many dangerous animals, including ferrophage moles, still existed on Krypton. Kryptonians had to use their advanced technology to survive.

Over 200,000 years ago, Krypton had developed scientific advancements far beyond those of present-day Earth, and had discovered a way to conquer disease and aging by perfecting cloning; vast banks of clones, kept in stasis, held multiple copies of each living Kryptonian so that replacement parts were always available in the event of injury. All Kryptonians were now effectively immortal, "with all the strength and vigor of youth maintained,"[6] and for millennia they enjoyed an idyllic, sensual existence in an Arcadian paradise.[7]

100,000 years later Kryptonian society was tipping toward decadence and eventually political strife resulted from the debate as to whether clones were sentient beings and should have rights (sparked by the presence of an alien missionary known as The Cleric, who carried "The Eradicator").[1] Eventually this disagreement led to open violent conflict. A woman named Nyra, seeking what she considered a suitable mate for her son, Kan-Z, had one of her younger clones removed from stasis. The clone gained full sentience and was presented to society as a normal woman. When Kan-Z discovered that his fiancée was in fact his mother's clone, he killed the clone and then publicly killed his mother, and also attempted his own suicide before being stopped. This key incident ignited the Clone Wars which lasted for a thousand years, during which Kryptonian science was turned to warfare and several super-weapons were developed and used. Among them was the device known as the Destroyer.

Although the Eradicator's effects (altering the DNA of all Kryptonian lifeforms so that they would instantly die upon leaving the planet) were felt immediately, the Destroyer's effects were possibly more significant: by the time the Kryptonian government admitted defeat and abolished the clone banks, a pro-clone rights terrorist faction known as Black Zero had started the Destroyer, a device which functioned as a giant nuclear gun, projecting massive streams of nuclear energy into the core of Krypton, intended to trigger an explosive chain reaction within Krypton's core almost immediately.

The use of the Destroyer eliminated the post-Crisis city of Kandor, but it was believed at the time that the device had been stopped before it could achieve planetary destruction (by Van-L, an ancestor of Jor-El). Centuries later, Jor-El himself would discover that the reaction had only been slowed to a nearly imperceptible rate and would eventually destroy the planet as intended.


Though it survived the war, Krypton was scarred deeply by it. The formerly lush garden world was burned and blasted to mostly a lifeless desert, and a sterile, emotionally dead civilization—much unlike its predecessor—emerged. The population became isolated from one another in widely separated technological citadels and shunned all personal and physical contact. Procreation became a matter of selecting compatible genetic material that would then be placed within an artificial womb called a "birthing matrix". The isolationist planetary government forbade exploring space and communicating with other worlds.

The young scientist Jor-El was born into this world. By his adult years, the mysterious "Green Plague" was killing Kryptonians by the thousands, and upon researching the matter, Jor-El discovered that its cause was growing radiation produced by Krypton's increasingly unstable core. This process was going to cause the planet to explode.

Unable to convince his associates to abandon tradition and consider escape, and reasoning that modern Kryptonian society had grown cold, unfeeling and sterile, Jor-El removed the Eradicator's planetary binding genes from his unborn son Kal-El's genetic pattern, took Kal-El's birthing matrix and attached a prototype interstellar propulsion system to the vessel.[1][8] Just as the planet began to shake apart, he launched the matrix towards Earth, where it would open and give birth to the infant upon landing (the post-Crisis Superman therefore was considered to be technically "born" on Earth). Jor-El was not only determined that his son would survive the death of his birthworld, but that he would grow up on a world that vibrantly embraced living, as his forbears once did.

The Last Son of Krypton

A central theme of this version of the Superman mythos was that the character was to remain the last surviving remnant of Krypton. Thus, Silver Age elements such as Supergirl, Krypto, and Kandor had never existed in this version (though post-Crisis versions of these elements were eventually reintroduced).

The supervillain Doomsday was revealed in the 1990s as a being genetically engineered by Bertron, an alien scientist, on an ancient Krypton. Doomsday left the planet after killing Bertron and Krypton's natives found the remains of Bertron's lab, thus obtaining the knowledge of cloning.

In the newer continuity, Superman also became aware of his alien heritage only sometime after his debut as a superhero - initially assuming himself to be a human mutated in some manner and launched as part of an Earth space program - when a holographic program encoded into the craft which brought him to Earth uploaded the information into his brain (although Lex Luthor had earlier discovered his alien heritage when his attempts to create a clone of Superman were complicated by the unexpected x-factor of Superman's alien DNA).

Revisiting Krypton

In Action Comics #600 (May 1988), Krypton was close enough to Earth that the radiation from its explosion (traveling only at light speed) was able to reach Earth.

In a 1988 storyline, Superman traveled to the former site of Krypton to discover that the planet was slowly reforming from the vast sphere of debris remaining. It would take millions of years before the planet would be solid again. This sphere of debris had been turned to Kryptonite by the planet's destruction, and the radiation caused Superman to have a hallucination in which the entire population of Krypton came to Earth and colonized the already inhabited planet, prompting Jor-El to initiate a Terran-based resistance movement, pitting him against his estranged wife Lara and now-grown son Kal-El, at which point the hallucination ended [9]

In Superman: The Man of Steel Annual #3, "Unforgiven" - an Elseworlds tale - Jor-El convinces the Science Council to relocate selected Kryptonians to Earth.[10]

In a 1999 Starman storyline, Jack Knight became lost in time and space, and landed on Krypton several years before its destruction, meeting Jor-El as a young man. The story implies that it was this early meeting with a Terran that led Jor-El to study other worlds and eventually choose Earth as the target for his son's spacecraft; at the story's end, Jack gives Jor-El a device with the coordinates and images of Earth.[11]

In a 2001–2002 storyline, an artificial version of the pre-Crisis Krypton was created in the Phantom Zone by Brainiac 13, a descendant of the original Brainiac who had traveled back in time to the present.[12] This version of Krypton was based on Jor-El's favorite Kryptonian historical period.[13]

Superman: Birthright

In the 2004 mini-series Superman: Birthright, a new retelling of Superman's origin and early years, Mark Waid located Krypton in the Andromeda Galaxy 2.5 million light-years away, and adopted elements from several previous versions of the planet.[14] Although usually depicted as a red giant or red supergiant, in this story Rao is mentioned by Jor-El to be a red dwarf.

In previous comic versions, it was assumed the "S" shield on Superman's costume simply stood for "Superman"; in Birthright, Waid presented it as a Kryptonian symbol of hope; he borrowed and modified a concept from Superman: The Movie, wherein the "S" was the symbol of the House of El, Superman's ancestral family.

The series reversed many elements of John Byrne's The Man of Steel, reverting the planet and associated characters to their Silver Age versions, to more closely resemble their depictions in the Smallville television series and the Superman movies.[14]

Post-Birthright revisions

Beginning with Infinite Crisis, writer Geoff Johns began laying subtle hints to a new origin for Superman. Last Son, a storyline co-written by Geoff Johns and Superman film director Richard Donner, further delves into this version of Krypton which reintroduces General Zod and the Phantom Zone criminals into mainstream continuity. With art by Adam Kubert, the design of Kryptonian society is distinct yet again from Birthright, incorporating elements of both pre-Crisis on Infinite Earths continuity and Donner's work on the first two Christopher Reeve films, in particular the notion of Krypton's Council threatening Jor-El with harsh punishment were he to make public his predictions of their planet's imminent doom.[15] This variation of Krypton's past was again seen in flashbacks during Johns' Brainiac and New Krypton story arcs. The very different depictions of Kryptonian clothing in the Golden and Silver Age comics, in the Christopher Reeve films, and in John Byrne's The Man of Steel all appeared in Johns' Superman: Secret Origin, (which superseded Superman: The Man of Steel and Superman: Birthright).

Multi-ethnic versions of Kryptonians that resemble Africans and Asians have also made appearances in the stories. Previously, "black" Kryptonians were mainly confined within the Kryptonian continent of Vathlo Island, but a 2011 storyline depicted Kryptonians resembling Black and Asian humans who were more integrated into Kryptonian society than they were in the Silver and pre-Modern Age DC Universe.[16]

The New 52

Following Grant Morrison's run on Action Comics, Krypton is again a scientific and cultural utopia, and Kryptonians themselves are highly intelligent, even from infancy; Morrison describes Krypton as “the planet of your dreams. A scientific utopia. I wanted to explore Krypton as the world of super people. What would happen if they worked it all out, if they lived for 500 years with amazing technology?” Cody Walker elaborates on this, saying, "Kal-El is the next step in evolution physically, but he comes from a planet that is the next stage in evolution as well. If his strength makes him the Man of Steel, then the ideologies that rule his planet make Superman the Man of Tomorrow."[17] In Action Comics #14 (January 2013 cover date, published November 7, 2012) astrophysicist Neil deGrasse Tyson appears as a character in the story. He determines that Krypton orbited the red dwarf LHS 2520 in the constellation Corvus 27.1 lightyears from Earth. Tyson assisted DC Comics in selecting a real-life star that would be an appropriate parent star to Krypton. He picked Corvus, which is Latin for "Crow",[18][19] because Superman's high school mascot is a Crow.[20][21] In a 2012 round-table discussion, Tyson stated that he chose to use real science when finding Krypton's location. He explained that many artists may only use bits and pieces of science, allowing for greater latitude in their creativity, but, he said, he wanted to show that using real science, particularly astrophysics, allows for just as much creativity.[22]

In other media


The first non-comics version of Krypton was presented in the debut storyline of the 1940s Superman radio series. In the radio show, Krypton was part of our Solar System, a Counter-Earth sharing Earth's orbit but on the opposite side of the Sun, hidden from view of the Earth ("Krypton" derives from the Greek word for "hidden"). Some comics of the early 1950s suggested a similar theory, but in general the comics have depicted Krypton as being in a far-away star system.





Superman: The Movie

In the first feature-length Superman film in 1978, a vastly less idyllic image of Krypton is presented. Whereas in the comics Krypton was colorful and bright, the film depicts the planet with stark white terrain of jagged frozen plateaus under heavy, dark skies. The planet is threatened by their sun turning into a supernova. Jor-El unsuccessfully attempts to persuade the council of elders to immediately evacuate the planet.

Kryptonians themselves are portrayed as coolly cerebral and morally enlightened, clad in stark white body suits emblazoned with each family's house symbol. The architecture features halls of white crystal under crystalline arches. The crystalline motif was employed not only in the architecture, but in the landscape and technology as well, suggesting that the entire planet had been adapted and altered by Kryptonian influence. In 1948, Krypton was ultimately destroyed when its red sun began to collapse; the planet was pulled into the sun and steadily crushed, then exploded in the ensuing supernova. When Krypton is destroyed, fragments from the planet are launched into space, resulting in the creation of a harmful radioactive substance known as kryptonite.

Both Jor-El and Lara preserve some part of their "essence" (in the form of virtual copies of themselves) in the starship that brings their child to Earth. On Clark Kent's eighteenth birthday, a glowing crystal reveals itself in the ship and compels Clark to take it north. He eventually reaches the Arctic, where the crystal constructs the massive crystalline Fortress of Solitude. Inside, an artificially intelligent hologram of Jor-El appears to him and initiates twelve years of Kryptonian education. These virtual versions of Jor-El and Lara remain as constructs within the Fortress throughout the series.

Superman's symbol is given a Kryptonian origin in the film. Male Kryptonians are shown wearing unique symbols on the chests of their robes, similar to a family crest; Jor-El and Kal-El wear the familiar S-shield, which Lois Lane later assumes to be the letter S from the familiar Latin alphabet, and thus dubs him "Superman".

Superman Returns

The 2006 movie Superman Returns presents a version of Krypton almost identical to Superman. In the beginning of the film, scientists discover remains of Krypton, and Superman leaves Earth for five years to look for it. His ship is seen leaving the dead planet. The planet is destroyed when the red supergiant Rao becomes a supernova.

Superman Returns extends the crystalline Kryptonian technology from Superman which allowed young Clark Kent to "grow" the Fortress of Solitude. Kryptonian crystals are able to grow huge land masses and incorporate the properties of the surrounding environment; a sliver taken from one of the crystals used to test the theory causes Lex Luthor's basement to be filled with a huge crystal structure. Growing land in this manner causes widespread power failure. Lex Luthor later combines one of the crystals with Kryptonite and shoots it into the ocean, creating what he calls "New Krypton". Superman uses his heat vision to get under the crust of the island and he then throws it into space.

The novelization by Marv Wolfman states that one of Superman's ancestors helped civilize Krypton long ago.

Man of Steel

The 2013 film Man of Steel adds strong dystopian elements to Krypton and its fate. The planet is portrayed as having an Earth-like terrain composed of mountains, canyons and oceans. The planet is 8.7 billion years old and approximately 27.1 light years from Earth. Its parent star Rao is depicted as a 13 billion year old red dwarf sun. Its gravity is much higher than that of Earth, and its atmospheric composition is unsuitable for humans. It is also shown to have a natural satellite. Kryptonian society is divided into houses, such as the House of El. Citizens wear the crests of their house over their chests, which hold meanings such as "hope."

Kryptonian civilization is at least 100,000 years old and many millennia more advanced than human civilization on Earth, and had begun exploring the Milky Way Galaxy. Kryptonians later abandon these projects in favor of isolationism and artificial population control, engineering newborns for pre-determined roles in society. The planet's resources were strained, and the stability of the planet was threatened by careless mining of the planet's core. As Jor-El attempts to warn the Science Council of their folly, General Zod stages a coup. In hopes of preserving the Kryptonian race, Jor-El steals the genetic Codex of the planet (a list holding the DNA pattern of everyone yet to be born on Krypton) and infuses it into the cells of Kal-El, the first natural-born child on Krypton in centuries, and sends his son to Earth. Zod kills Jor-El and is arrested by the authorities. He and his followers are banished to the Phantom Zone shortly before Krypton is destroyed.

Batman v Superman: Dawn of Justice

In the 2016 film Batman v Superman: Dawn of Justice, Luthor learns the Council of Krypton banished the creations of "Kryptonian Deformities".


Last Son of Krypton

The 1978 novel Last Son of Krypton by Elliot S! Maggin contains descriptions of Krypton, mainly referencing the Silver Age version; it describes the planet as a "failed star" with massive surface gravity and extremely hostile, glaciated conditions, which forced extreme adaptation and rapid evolution in the descendants of humanoid space travelers (and their dogs) who became stranded on its surface in prehistory. This led to an extremely strong, dense, and durable Kryptonian species with unusual physical properties. Maggin describes the rise of a civilization which uses geothermal heat as its primary power source, developing science and technology, but finding it difficult to escape the massive world's gravity. Eventually its internal nuclear reactions led to Krypton's explosion.

The Last Days of Krypton

Novelist Kevin J. Anderson presents approximately the last Earth year before Krypton's destruction in the 2007 novel The Last Days of Krypton. Depictions of the planet's society and culture loosely resemble elements from the motion picture Superman, the television series Smallville, and post-Infinite Crisis interpretations, although numerous similarities to Silver Age depictions of Krypton are also apparent.
