1205 Ebella
1205 Ebella is a relatively eccentric asteroid from the central regions of the asteroid belt, approximately 5.5 kilometers in diameter. It was discovered by astronomer Karl Reinmuth at Heidelberg Observatory on 6 October 1931. The asteroid was named after German astronomer Martin Ebell.
Orbit and classification
Ebella orbits the Sun in the central main-belt at a distance of 1.8–3.2 AU once every 4.04 years. Its orbit has an eccentricity of 0.27 and an inclination of 9° with respect to the ecliptic. As no precoveries were taken and no prior identifications were made, the asteroid's observation arc begins at Heidelberg with its official discovery observation.Physical characteristics
Diameter and albedo
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Ebella measures 5.474 kilometers in diameter and its surface has an albedo of 0.214, which is typical for stony S-type asteroids.Based on a generic magnitude-to-diameter conversion, it measures 6.0 kilometers in diameter using an absolute magnitude of 13.50 with an assumed albedo of 0.20.
