2907 Nekrasov : ウィキペディア英語版 | 2907 Nekrasov 2907 Nekrasov is an asteroid discovered by Nikolai Stepanovich Chernykh on October 3, 1975. Its provisional designation was 1975 TT2. Nekrasov has an absolute magnitude of 11.50 and is thus assumed to be 13 km to 30 km in diameter〔(NASA Glossary: Absolute Magnitude )〕 Nekrasov orbits in the main asteroid belt between Mars and Jupiter and is not a near-Earth asteroid.〔(JPL Small-Body Database Browser )〕 However, it has been incorrectly described in some newspaper reports as likely to collide with the Earth on December 16, 2880.〔(''Defense News'' )〕〔()〕 These reports have confused it with a smaller asteroid, (29075) 1950 DA, which has been proposed as likely to collide with the Earth on March 16, 2880.〔()〕 ==References==
