2815 Soma, provisional designation 1982 RL, is a
Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona, in the United States .[11] It is named for the mechanical puzzle Soma cube.[3]
Orbit and classification
Soma is a member of the
Crimea-Nauchnij, 12 years prior to its official discovery at Anderson Mesa.[11]
Diameter and albedo
According to the survey carried out by NASA's
albedo of 0.365 and 0.3207, respectively.[7][9] The Collaborative Asteroid Lightcurve Link adopts Peter Pravec's revised WISE-data, that is, an albedo of 0.2273 and a diameter of 7.067 kilometers with an absolute magnitude of 12.98.[4][8]

Secondary
In March 2011, photometric observations revealed that Soma is a synchronous
