1957 Angara, provisional designation 1970 GF, is a stony asteroid from the outer region of the asteroid belt, approximately 18 kilometer in diameter. It was discovered by Russian female astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on 1 April 1970.[8]
The S-type asteroid is a member of the Eos family. It orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,904 days). It has a rotation period of 3.67 hours[7] and a geometric albedo of about 0.11–0.14.[4][5]
It is named for the over 1000-mile long Siberian Angara River that drains Lake Baikal.[2]
