Overview
2010 JO33 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 JO33 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.
2010 JO33 orbits the sun every 1,450 days (3.97 years), coming as close as 1.02 AU and reaching as far as 4.01 AU from the sun. Based on its brightness and the way it reflects light, 2010 JO33 is probably between 0.027 to 0.059 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2010 JO33's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2010 JO33 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 10, 2026 | 23,091,408 | 12.620 |
| May 1, 2050 | 14,124,234 | 8.596 |
| June 6, 2054 | 13,892,706 | 8.412 |
| May 6, 2099 | 23,021,802 | 7.738 |
| June 15, 2144 | 22,109,733 | 9.791 |
