99251 (2001 LM) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2001 LM as potentially hazardous because its orbit does not bring it close to Earth.
2001 LM orbits the sun every 2,890 days (7.91 years), coming as close as 3.13 AU and reaching as far as 4.82 AU from the sun. 2001 LM is about 10.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
2001 LM's orbit is 2.13 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2001 LM's orbit is determined by observations dating back to Feb. 14, 1997. It was last officially observed on May 22, 2023. The IAU Minor Planet Center records 1,167 observations used to determine its orbit.
