3D model of Asteroid 2063 Bacchus (Scott Hudson)

The Apollo, Venus- and Mars-crosser asteroid 2063 Bacchus was discovered on April 24, 1977 by Charles T. Kowal at the Palomar Observatory. In March 1996 radar imaging of the asteroid was conducted at the Goldstone Observatory under the direction of JPL scientists Steven Ostro and Lance Benner. Optical observations were conducted by Petr Pravec, Marek Wolf, and Lenka Šarounová during March and April 1996.

The asteroid is thought to be about 1.1×1.1×2.6 km in size. It is classified as a Q-type asteroid.

Its name derives from the Roman god Bacchus.
