2063 Bacchus

Orbit and classification

Bacchus orbits the Sun at a distance of 0.7–1.5 AU once every 1 years and 1 month (409 days). Its orbit has an eccentricity of 0.35 and an inclination of 9° with respect to the ecliptic. The asteroid's observation arc begins with its official discovery observation at Palomar. Due to its eccentric orbit, it is also a Venus-crosser.

Approaches

Bacchus has an Earth minimum orbital intersection distance of 0.0677 AU, which corresponds to 26.4 lunar distances. On 31 March 1996, it passed 0.0677525 AU from Earth.

Physical characteristics

In the SMASS classification, Bacchus is a Sq-type, that transitions from the common S-type asteroids to the Q-type asteroids. It is a contact binary with bilobate shape.

In March 1996 radar observations 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. Optical observations were conducted by Petr Pravec, Marek Wolf, and Lenka Šarounová during March and April 1996. It was also photometrically observed by American astronomer Brian Warner in 2015.

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Bacchus measures 1.03 kilometers in diameter and its surface has an albedo of 0.19. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 1.05 kilometers based on an absolute magnitude of 17.25.

Naming

This minor planet was named for the Roman god Bacchus (Dionysus).The official was published by the Minor Planet Center on 1 August 1978 (M.P.C. 4421).
