2018 XM2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 XM2 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.
2018 XM2 orbits the sun every 510 days (1.40 years), coming as close as 0.95 AU and reaching as far as 1.55 AU from the sun. Based on its brightness and the way it reflects light, 2018 XM2 is probably between 0.022 to 0.049 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 XM2's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2018 XM2 has 1 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Dec. 5, 2025||18,798,132||14.801|
2018 XM2's orbit is determined by observations dating back to Dec. 10, 2018. It was last officially observed on Dec. 14, 2018. The IAU Minor Planet Center records 44 observations used to determine its orbit.
