2278 Götz, provisional designation 1953 GE, is a dark background asteroid from the inner regions of the asteroid belt's background population, approximately 12 kilometers (7.5 miles) in diameter. It was discovered on 7 April 1953, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany.[1] The F/C-type asteroid was named after astronomer Paul Götz.[2]
Orbit and classification
Götz is non-family asteroid of the main belt's background population (formerly being classified as a member of the Nysa family by Zappala).[4][5] It orbits the Sun in the inner main-belt at a distance of 2.1–2.8 AU once every 3 years and 10 months (1,403 days). Its orbit has an eccentricity of 0.15 and an inclination of 4° with respect to the ecliptic.[3]
The body's observation arc begins with its official discovery observation at Heidelberg. Simultaneously, the asteroid was also observed at the Almaty Observatory in Kazakhstan (210).[1]
Naming
This minor planet was named in memory of Paul Götz (1883–1962), a German astronomer and discoverer of minor planets, who was the first assistant of Max Wolf at Heidelberg in the early 1900s, using the observatory's Bruce telescope and 0.15-meter astrograph.[2] The official naming citation was proposed and prepared by G. Klare and L. D. Schmadel and was published by the Minor Planet Center on 27 June 1991 (M.P.C. 18447).[2][7]
Physical characteristics
In the Tholen classification, the asteroid has an ambiguous spectral type, closest to the F-type and somewhat similar to the carbonaceous C-type asteroid.[3]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Götz measures 11.769 kilometers in diameter and its surface has an albedo of 0.039.[6]
Rotation period
As of 2018, no rotational lightcurve of Götz has been obtained from photometric observations since its discovery in 1953. The asteroid's rotation period, pole and shape remain unknown.[3][8]
