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 observations of the asteroid were conducted at the Goldstone Observatory under the direction of JPL scientists Steven Ostro and Lance Benner, allowing the construction of a model of the object [1]. Optical observations were conducted by Petr Pravec, Marek Wolf, and Lenka Šarounová during March and April 1996.
The asteroid is about 1.1×1.1×2.6 km in size and has a bilobate shape. It is classified as a Q-type asteroid.
Its name derives from the Roman god Bacchus.
