Overview

2002 XQ40 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 XQ40 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.

2002 XQ40 orbits the sun every 407 days (1.11 years), coming as close as 0.70 AU and reaching as far as 1.45 AU from the sun. Based on its brightness and the way it reflects light, 2002 XQ40 is probably between 0.092 to 0.206 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2002 XQ40's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2002 XQ40 has 20 close approaches predicted in the coming decades:
