1889 Pakhmutova, provisional designation 1968 BE, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 35 kilometers in diameter.

It was discovered by Russian astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on 24 January 1968.[13] The asteroid was named after Russian composer Aleksandra Pakhmutova.[2]

Orbit and classification

Pakhmutova orbits the Sun in the

Johannesburg Observatory in 1942. Its first used observation was made in 1968, when it was identified as 1966 US at the discovering observatory, extending the body's observation arc by 2 years prior to its official discovery observation.[13]

Physical characteristics

Pakhmutova has been characterized as a carbonaceous C-type asteroid.[3]

Diameter and albedo

This asteroid has a mean-diameter between 33.53 and 37.68 kilometers, and an

NEOWISE surveys.[4][5][6][7][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0574 and a diameter of 33.41 kilometers with an absolute magnitude of 11.1.[3]

Rotation period and poles
