Overview
2010 KR10 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 KR10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2010 KR10 orbits the sun every 1,170 days (3.20 years), coming as close as 0.90 AU and reaching as far as 3.44 AU from the sun. Based on its brightness and the way it reflects light, 2010 KR10 is probably between 0.335 to 0.748 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
Close Approaches
2010 KR10'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.
2010 KR10 has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 13, 2061 | 11,245,568 | 14.346 |
| Oct. 19, 2077 | 24,279,711 | 16.823 |
| June 22, 2170 | 20,565,201 | 16.338 |
| June 20, 2186 | 26,349,765 | 17.395 |
