Overview
2020 MN3 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2020 MN3 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.
2020 MN3 orbits the sun every 609 days (1.67 years), coming as close as 1.02 AU and reaching as far as 1.79 AU from the sun. Based on its brightness and the way it reflects light, 2020 MN3 is probably between 0.064 to 0.143 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2020 MN3's orbit is 0.05 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.
2020 MN3 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 24, 2020 | 19,017,621 | 9.297 |
| June 25, 2025 | 18,255,448 | 9.315 |
| June 24, 2030 | 19,838,086 | 9.289 |
| July 10, 2168 | 19,137,246 | 11.981 |
| July 11, 2173 | 22,364,333 | 12.409 |
| July 13, 2178 | 27,984,761 | 13.185 |
