Overview

88213 (2001 AF2) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 AF2 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.

2001 AF2 orbits the sun every 340 days (0.93 years), coming as close as 0.39 AU and reaching as far as 1.52 AU from the sun. 2001 AF2 is about 0.9 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, comparable in size to the Golden Gate Bridge.

Close Approaches

2001 AF2's orbit is 0.17 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2001 AF2 has 9 close approaches predicted in the coming decades:
