2007 VE191 is a sub-kilometerasteroid, classified asnear-Earth asteroid of theApollo group that was listed on theSentry Risk Table.[3]
It is estimated to be roughly 63 meters in diameter. In 2015 it was known to have a 1 in 63,000 chance ofimpacting Earth on 27 November 2015.[3] However, thenominal best-fit orbit showed that2007 VE191 would be roughly 0.5 AU (75,000,000 km; 46,000,000 mi) from Earth on 27 November 2015 with anapparent magnitude of roughly +25 in theconstellation ofVirgo about 50 degrees from the Sun,[5] 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,[6] but was still listed atNEODyS with odds of 1 in 3 million for 27 November 2015 during the approach window.[7]
2007 VE191 was discovered on 15 November 2007 by theMount Lemmon Survey at an apparent magnitude of 20 using a 1.5-meter (59 in)reflecting telescope.[1] On 28 November 2007, it passed 0.0128 AU (1,910,000 km; 1,190,000 mi) from Earth.[8]2007 VE191 has anobservation arc of 13 days with anuncertainty parameter of 7, which means its orbit is poorly constrained.[2]2007 VE191 was last observed on 28 November 2007.[2] By 1 December 2007, the asteroid had faded to below magnitude 25.[9]
With anabsolute magnitude of 23.6,[2]2007 VE191 is about 50–110 meters in diameter.[4]
