Overview

152931 (2000 EA107) is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 EA107 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2000 EA107 orbits the sun every 327 days (0.90 years), coming as close as 0.51 AU and reaching as far as 1.35 AU from the sun. 2000 EA107 is about 1.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 2000 EA107 has been observed. It completes a rotation on its axis every 4.14 hours.

2000 EA107's spectral type None (Tholen) / Q (SMASSII) indicates that it is likely to contain .

Close Approaches

2000 EA107's orbit is 0.16 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2000 EA107 has 7 close approaches predicted in the coming decades:
