is a carbonaceous, Themistian asteroid from the outer region of the asteroid belt, about 10 kilometers in diameter. It was discovered on 21 March 1993, by the Uppsala-ESO Survey of Asteroids and Comets (UESAC) at ESO's La Silla Observatory site in northern Chile.
The dark C-type asteroid is a member of the Themis family, a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.8–3.4 AU once every 5 years and 5 months (1,987 days). Its orbit has an eccentricity of 0.11 and an inclination of 1° with respect to the ecliptic. It was first identified as at Heidelberg in 1933, extending the body's observation arc by 60 years prior to its official discovery observation at La Silla.
In 2014, two rotational lightcurves of this asteroid were obtained from photometric observations in the R-band at the U.S. Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 3.4735 and 3.470 hours with a brightness variation of 0.10 and 0.13 in magnitude, respectively .
The Collaborative Asteroid Lightcurve Link (CALL) assumes a low albedo of 0.08 for the asteroid's surface and calculates a diameter of 9.9 kilometers, based on an absolute magnitude of 13.38.
As of 2017, the asteroid has not been named.
