2002 MN is a 73-meter Apollo near-Earth asteroid that on 14 June 2002 passed Earth at a distance of 0.0008 AU (120,000 km; 74,000 mi),[3] about one third the distance to the Moon (0.3 LD).[5] The close approach was second only to the Earth approach by the 10-meter asteroid Template:Mpl.[5] 2002 MN was discovered on 17 June 2002, three days after closest approach.[1] Its mass and relative velocity were in the same general range as the object ascribed to the Tunguska event of 1908, which leveled over 2,100 km2 (800 mi2) of trees in Siberia.
2002 MN was estimated to have a 1 in 360,000 chance of Earth impact sometime after 2070,[4] but further observations in July 2024[6] ruled this out, and the object was removed from the risk list.
