1951 Lick, provisional designation 1949 OA, is a rare-type asteroid and Mars-crosser, approximately 5.6 kilometers in diameter.
[3] In the SMASS taxonomic scheme, Lick's spectral type is that of a rare A-type asteroid with a surface consisting of almost pure olivine.
[11] In July 2008, a rotational lightcurve was obtained from photometric by astronomer Brian D. Warner at his Palmer Divide Observatory in Colorado, United States.
[8] According to 3 observations taken by the Infrared Astronomical Satellite IRAS, Lick measures 5.57 kilometers in diameter and its surface has an albedo of 0.09.
[5] The Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS and derives an albedo of 0.10 and a diameter of 5.59 kilometers with an absolute magnitude of 14.35.
