Шаблон:Mp is a very small Apollo asteroid that passed near Earth at an altitude of Шаблон:Convert on 2 March 2009 at 13:44 UTC. It was discovered by Australian astronomers with the Siding Spring Survey at the Siding Spring Observatory on 27 February 2009, only three days before its closest approach to the Earth.[1][2] Its estimated diameter is between 15 and 23 metres.[3] This is about the same size as a hypothetical object that could have caused the Tunguska event in 1908.[4]

BBC News Online cites the minimum distance as Шаблон:Convert (about 1/5 lunar distances).[4][5] Шаблон:Mp passed farther away (40 thousand miles versus 4 thousand miles) but was substantially larger than 2004 FU162, a small asteroid about 6 m (20 ft) across which came within about Шаблон:Convert in 2004,[4] and is more similar in size to 2004 FH. With an observation arc of 7 days and an uncertainty parameter of 3, the asteroid will make its next close encounter with Earth on 29 February 2056 and then potentially around 3 March 2067.[3]
