Overview

2002 KK8 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2002 KK8 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2002 KK8 orbits the sun every 997 days (2.73 years), coming as close as 1.04 AU and reaching as far as 2.86 AU from the sun. Based on its brightness and the way it reflects light, 2002 KK8 is probably between 0.168 to 0.375 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2002 KK8's orbit is 0.03 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 KK8 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
June 3, 2043 10,598,473 14.926
June 15, 2073 16,949,376 15.440
June 2, 2114 14,606,891 15.076
June 13, 2144 10,629,264 15.128
June 2, 2185 13,204,264 15.079
