1205 Ebella (provisional designation 1931 TB1) 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. [5]
Ebella orbits the Sun in the central main-belt at a distance of 1.8–3.2 AU once every 4.04 years (1,474 days). Its orbit has an eccentricity of 0.27 and an inclination of 9° with respect to the ecliptic. [1] As no precoveries were taken and no prior identifications were made, the asteroid's observation arc begins at Heidelberg with its official discovery observation. [5]
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. [3]
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. [4]
As of 2017, no rotational lightcurve of Ebella has been obtained from photometric observations. The asteroid's rotation period, poles and shape still remain unknown. [1] [6]
This minor planet was named after Carl Wilhelm Ludwig Martin Ebell (1871–1944) an astronomer from Neuruppin, Germany, who was on the editorial team of the renowned astronomical journal Astronomische Nachrichten . The official naming citation was published by Paul Herget in The Names of the Minor Planets in 1955 ( H 112 ). [2]
