Notes

  1. For a list of current Earth close approaches see NEO Earth Close Approaches
  2. Distance from the center of Earth to the center of the object. See the NASA/JPL Solar System Dynamics Glossary: Geocentric. Earth has a radius of approximately 6,400 km.
  3. For asteroids without a well determined size an albedo of 0.05 is assumed. An albedo of 0.05 establishes an approximate upper limit to the size of the asteroid.
