Overview
2016 XM is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 XM as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2016 XM orbits the sun every 935 days (2.56 years), coming as close as 0.96 AU and reaching as far as 2.79 AU from the sun. Based on its brightness and the way it reflects light, 2016 XM is probably between 0.260 to 0.581 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
2016 XM's orbit is 0.02 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.
2016 XM has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 2, 2040 | 8,220,680 | 10.899 |
| April 13, 2063 | 6,175,664 | 12.397 |
| April 1, 2104 | 10,330,296 | 10.698 |
| April 22, 2127 | 21,136,332 | 14.684 |
| March 28, 2168 | 13,832,480 | 10.473 |
| April 14, 2191 | 6,234,234 | 12.364 |
Images and Observations
2016 XM's orbit is determined by observations dating back to Nov. 6, 2016. It was last officially observed on May 24, 2022. The IAU Minor Planet Center records 86 observations used to determine its orbit.
