[10] The stony S-type asteroid, has been characterized as a Q-V-type by PanSTARRS photometric survey.
[a] The lightcurve gave a rotation period of 7.520 to 7.589 hours with a brightness variation between 0.12 and 0.22 in magnitude (U=3/3-/3-/3).
According to the original data from the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 4.8 kilometers in diameter and its surface has an albedo of 0.31,[5] while the Collaborative Asteroid Lightcurve Link agrees with the revised NEOWISE data[4] which gave an albedo of 0.26 and a diameter of 4.5 kilometers with an absolute magnitude of 13.8.
[3] This minor planet was named in honour of renowned Russian mathematician and physicist Andrei Sakharov (1921–1989), who received the Nobel Peace Prize in 1975.
[2] The official naming citation was published by the Minor Planet Center on 1 August 1981 (M.P.C.
