Overview

163683 (2002 YP2) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 YP2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2002 YP2 orbits the sun every 723 days (1.98 years), coming as close as 0.49 AU and reaching as far as 2.66 AU from the sun. Based on its brightness and the way it reflects light, 2002 YP2 is probably between 0.400 to 0.895 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2002 YP2's orbit is 0.02 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.

2002 YP2 has 10 close approaches predicted in the coming decades:
