Шаблон:Use dmy dates Шаблон:Infobox planet Шаблон:Mp, provisional designation Шаблон:Mp, is a sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group that had a small chance of impacting Earth in 2029.[1][2]

It was discovered on 20 September 2006, by the Spacewatch project at the University of Arizona using the dedicated 0.9-meter telescope at Kitt Peak National Observatory. The asteroid was calculated to measure 377 meters in diameter with a mass of Шаблон:Val.[2]

Description

Шаблон:Mp had a 1 in 42,000 chance of impacting Earth on 22 January 2029. By 29 October 2006, it was listed with a Torino Scale impact risk value of 0. It was removed from the Sentry Risk Table on 23 November 2006.[3] It is now known that on 28 January 2029, the asteroid will be Шаблон:Convert from Earth.[4]

It is a near-Earth asteroid that received minor attention in late September and early October 2006 because initial observations indicated a higher than usual probability that it would strike the Earth in 2029. However, the Near-Earth Object (NEO) Office at NASA's Jet Propulsion Laboratory (JPL) removed Шаблон:Mp from its risk list as additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon through 2106. Similarly, NEODyS estimates show a zero impact probability through 2080.

Шаблон:Mp briefly led the Earth-impact hazard list from 27 September 2006 through 4 October 2006, temporarily displacing (144898) 2004 VD17 from the number one position. At the time, both held a Torino scale of level 1 and were the only asteroids to hold a Torino value greater than 0.

Even though Шаблон:Mp has an Earth MOID of Шаблон:Convert, the orbit and future close approaches are well determined with an orbital uncertainty of 0.[4] It is also an Earth-crosser and Mars-crosser asteroid.
