3917 Franz Schubert, provisional designation 1961 CX, is a bright background asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 15 February 1961, by astronomer Freimut Börngen at the Karl Schwarzschild Observatory in Tautenburg, Germany.[2] The asteroid was named after Austrian composer Franz Schubert.[3]
Orbit and classification
Franz Schubert is a non-family asteroid from the main belt's background population.[4] It orbits the Sun in the inner main-belt at a distance of 2.3–2.4 AU once every 3 years and 7 months (1,323 days; semi-major axis of 2.36 AU). Its orbit has an eccentricity of 0.02 and an inclination of 2° with respect to the ecliptic.[1]
The body's observation arc begins with its official discovery observation at Tautenburg in February 1961.[2]
Physical characteristics
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Franz Schubert measures 5.129 kilometers in diameter and its surface has a high albedo of 0.321.[5]
Rotation period
As of 2017, no rotational lightcurve of Franz Schubert has been from photometric observations. The asteroid's rotation period, shape and poles remain unknown.[1][6]
Naming
This minor planet was named after Austrian composer Franz Schubert (1797–1828).[3] The official naming citation was published by the Minor Planet Center on 20 February 1989 (M.P.C. 14208).[7]
