Overview

2008 UA202 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 UA202 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.

2008 UA202 orbits the sun every 384 days (1.05 years), coming as close as 0.96 AU and reaching as far as 1.10 AU from the sun. Based on its brightness and the way it reflects light, 2008 UA202 is probably between 0.023 to 0.100 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2008 UA202's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2008 UA202 has 2 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
May 18, 2028 12,869,148 4.866
