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]
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]
