Richard M. West.[2]
Classification and orbit
West orbits the Sun in the central main-belt at a distance of 2.4–3.0 AU once every 4 years and 5 months (1,625 days). Its orbit has an eccentricity of 0.12 and an inclination of 6° with respect to the ecliptic.[1] The asteroid observation arc begins at Heidelberg one month after its official discovery observation in March 1938.[9]
Physical characteristics
In the
SMASS classification, West is a common S-type asteroid.[1]

Diameter
According to the surveys carried out by the Japanese
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a much larger diameter of 26.64 kilometers using an absolute magnitude of 11.6.[6]
