Overview

368203 (2001 KO2) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 KO2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2001 KO2 orbits the sun every 1,430 days (3.92 years), coming as close as 0.95 AU and reaching as far as 4.02 AU from the sun. Based on its brightness and the way it reflects light, 2001 KO2 is probably between 0.205 to 0.459 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2001 KO2's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2001 KO2 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
June 7, 2048 13,191,427 15.382
May 16, 2075 12,511,254 12.651
June 17, 2098 25,370,674 17.867
June 9, 2125 14,348,015 15.525
