Template:Mp is a near-Earth asteroid that was discovered on 10 January 2010 at Grove Creek Observatory, Australia.[1][2]
Italian scientists Ernesto Guido and Giovanni Sostero told RIA Novosti that it had an orbital period of almost exactly one year and might be a spent rocket booster.[3] However, it was determined that it is a near-Earth asteroid.[4] On January 13, 2010 at 1246 UT it passed Earth at Script error: No such module "convert".,[1] about 1/3 of the distance from the Earth to the Moon (or 0.33 LD).
Based an estimated diameter of Script error: No such module "convert"., if 2010 AL30 had entered the Earth's atmosphere, it would have created a meteor air burst equivalent to between 50 kT and 100 kT (kilotons of TNT). The Nagasaki "Fat Man" atom bomb had a yield between 13–18 kT.[5]
It has an uncertainty parameter of 2 and has been observed by radar.[1] Radar observations show the asteroid is elongated and is about 30 meters in diameter.[6] It may be a contact binary.
