Шаблон:Mp is a sub-kilometer asteroid, classified as near-Earth asteroid of the Apollo group that was listed on the Sentry Risk Table.[1]

Description

It is estimated to be roughly 63 meters in diameter. In 2015 it was known to have a 1 in 63,000 chance of impacting Earth on 27 November 2015.[1] However, the nominal best-fit orbit showed that Шаблон:Mp would be roughly Шаблон:Convert from Earth on 27 November 2015 with an apparent magnitude of roughly +25 in the constellation of Virgo about 50 degrees from the Sun,[2] and the same nominal orbit gave a distance of closest approach to Earth of a little under 0.4 AU a few weeks earlier. It was removed from the Sentry Risk Table on 17 September 2015,[3] but was still listed at NEODyS with odds of 1 in 3 million for 27 November 2015 during the approach window.[4]

Шаблон:Mp was discovered on 15 November 2007 by the Mount Lemmon Survey at an apparent magnitude of 20 using a Шаблон:Convert reflecting telescope.[5] On 28 November 2007, it passed Шаблон:Convert from Earth.[6] Шаблон:Mp has an observation arc of 13 days with an uncertainty parameter of 7, which means its orbit is poorly constrained.[7] Шаблон:Mp was last observed on 28 November 2007.[7] By 1 December 2007, the asteroid had faded to below magnitude 25.[8]

With an absolute magnitude of 23.6,[7] Шаблон:Mp is about 50–110 meters in diameter.[9]
