Overview

85628 (1998 KV2) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1998 KV2 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.

1998 KV2 orbits the sun every 734 days (2.01 years), coming as close as 1.06 AU and reaching as far as 2.12 AU from the sun. 1998 KV2 is about 0.8 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 1998 KV2 has been observed. It completes a rotation on its axis every 2.82 hours.

Close Approaches

1998 KV2's orbit is 0.14 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.

1998 KV2 has 6 close approaches predicted in the coming decades:
