Near-Earth asteroid February 2018 yes #FFC2E0 2007 VE 191 Mt. Lemmon Survey (G96) 15 November 2007 2007 VE 191 NEOApollo 21 November 2025 (JD 2461000.5) 13 days(last seen 2007) 3.1100 AU Gm on on (Q) 0.71131 AU Gm on (q) 1.9107 AU Gm on (a) 0.62772 (e) 2.64 yr (964.66 d) 5.3848° (i) 244.09° (Ω) 274.22° (M) 254.29° (ω) ~63 meters50–110 meters 23.6 0.37319 ms /day (n) 7 0.00042694 AU km on 1.99054 AU Gm on 2007 VE 191 is a sub-kilometer asteroid, classified as a near-Earth asteroid of the Apollo group that was listed on the Sentry Risk Table. 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. However, the nominal best-fit orbit showed that 2007 VE 191 would be roughly 0.5 AU km mi on on from Earth on 27 November 2015 with an apparent magnitude of roughly +25 in the constellation of Virgo about 50 degrees from the Sun, 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, but was still listed at NEODyS with odds of 1 in 3 million for 27 November 2015 during the approach window. 2007 VE 191 was discovered on 15 November 2007 by the Mount Lemmon Survey at an apparent magnitude of 20 using a 1.5 m in on us reflecting telescope. On 28 November 2007, it passed 0.0128 AU km mi on on from Earth. 2007 VE 191 has an observation arc of 13 days with an uncertainty parameter of 7, which means its orbit is poorly constrained. 2007 VE 191 was last observed on 28 November 2007. By 1 December 2007, the asteroid had faded to below magnitude 25. With an absolute magnitude of 23.6, 2007 VE 191 is about 50–110 meters in diameter.
