Overview
499496 (2010 MR87) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2010 MR87 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 MR87 orbits the sun every 834 days (2.28 years), coming as close as 1.06 AU and reaching as far as 2.41 AU from the sun. 2010 MR87 is about 0.4 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.
Close Approaches
2010 MR87's orbit is 0.15 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.
2010 MR87 has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 1, 2026 | 28,346,362 | 18.838 |
| Oct. 6, 2115 | 22,817,932 | 19.877 |
| Oct. 3, 2131 | 27,951,462 | 18.907 |
