2052 Tamriko, provisional designation 1976 UN, is a stony Eoan asteroid from the outer regions of the asteroid belt, approximately 27 kilometers in diameter. It was discovered on 24 October 1976, by Richard Martin West at ESO's La Silla Observatory in northern Chile.[14] The asteroid was named after the discoverer's wife Tamara West.[2]

Orbit and classification

Tamriko is a member of the

606), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids.[4][15]: 23  It orbits the Sun in the outer main-belt at a distance of 2.8–3.3 AU once every 5 years and 3 months (1,905 days). Its orbit has an eccentricity of 0.08 and an inclination of 10° with respect to the ecliptic.[1]

The asteroid was first identified as A902 UB at

Heidelberg Observatory in October 1902. Its observation arc begins 24 years prior to the official discovery observation, with its identification 1952 FL at Goethe Link Observatory in March 1952.[14]

Physical characteristics

In the

Tholen classification, Tamriko is a stony S-type asteroid.[1]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.1225 and 0.158.[5][6][7][8][9]

The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, a standard albedo of 0.1225 and a diameter of 30.45 kilometers with an absolute magnitude of 10.48.[3]
