4709 Ennomos (1988 TU2) is a Jupiter trojan discovered on October 12, 1988 by Shoemaker, C. at Palomar. It is named after Ennomos, a Trojan hero in the Iliad.
Photometric observations of this asteroid during 1990 were used to build a light curve showing a rotation period of 12.275 ± 0.008 hours with a brightness variation of 0.47 ± 0.01 magnitude.[2]
