From Wikipedia, the free encyclopedia
2867 Šteins (provisional designation 1969 VC) is an irregular, diamond-shaped background asteroid from the inner regions of the asteroid belt, approximately 5 kilometers (3.1 miles) in diameter. It was discovered on 4 November 1969 by Soviet astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnij on the Crimean peninsula.[1] In September 2008, ESA's spacecraft Rosetta flew by Šteins, making it one of few minor planets ever visited by a spacecraft. The bright E-type asteroid features 23 named craters and has a rotation period of 6.05 hours.[8] It was named for Soviet Latvian astronomer Kārlis Šteins.[1]
