Near-Earth asteroid February 2018 yes #FFC2E0 2002 MN Apollo NEO Asteroid's near-miss with Earth - 21 June 2002 - New Scientist MIT Lincoln Laboratory 17 June 2002 22.04 yr 21 November 2025 (JD 2461000.5) 1.8163 AU Gm on 0.90900 AU Gm on 2.7236 AU Gm on on 0.49953 2.4478 yr (894.08 d) 1.0471° 85.291° 224.060° 131.599° ~73 m us(assumed)assumed 5.4e8 kg 23.7 0.40265° / day 0 0.000353729 AU km on 2.24701 AU Gm on 2002 MN is a 73-meter Apollo near-Earth asteroid that on 14 June 2002 passed Earth at a distance of 0.0008 AU km mi on on, about one third the distance to the Moon (0.3 LD). The close approach was second only to the Earth approach by the 10-meter asteroid 1994 XM 1. 2002 MN was discovered on 17 June 2002, three days after closest approach. Its mass and relative velocity were in the same general range as the object ascribed to the Tunguska event of 1908, which leveled over 800 mi2 km2 flip on of trees in Siberia. 2002 MN was estimated to have a 1 in 360,000 chance of Earth impact sometime after 2070, but further observations in July 2024 ruled this out, and the object was removed from the risk list. Notes assumed Diameter estimate based on an assumed albedo of 0.15.
