2010 JA is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 JA 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 JA orbits the sun every 490 days (1.34 years), coming as close as 0.86 AU and reaching as far as 1.57 AU from the sun. Based on its brightness and the way it reflects light, 2010 JA is probably between 0.007 to 0.031 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2010 JA'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 JA has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 13, 2022 | 22,094,685 | 6.789 |
| Sept. 21, 2026 | 10,081,757 | 6.679 |
| Oct. 3, 2030 | 8,287,992 | 9.891 |
| May 2, 2065 | 12,950,871 | 10.986 |
| June 27, 2073 | 22,412,537 | 6.906 |
| April 29, 2116 | 20,837,659 | 12.550 |
2010 JA's orbit is determined by observations dating back to May 4, 2010. It was last officially observed on May 8, 2010. The IAU Minor Planet Center records 90 observations used to determine its orbit.
2010 JA can be reached with a journey of 370 days. This trajectory would require a delta-v of 9.016 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 10,081 potential trajectories and launch windows to this asteroid.
