    4003 Schumann, provisional designation 1964 ED, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 35 kilometers in diameter.

    Contents

    The asteroid was discovered on 8 March 1964, by German astronomer Freimut Börngen at the Karl Schwarzschild Observatory in Tautenburg, Eastern Germany. [11] It was named after German composer Robert Schumann. [2]

    Orbit and classification

    Schumann orbits the Sun in the outer main-belt at a distance of 3.1–3.7  AU once every 6 years and 4 months (2,316 days). Its orbit has an eccentricity of 0.09 and an inclination of 5° with respect to the ecliptic. [1] The first precovery was obtained at Heidelberg Observatory in 1933, extending the asteroid's observation arc by 31 years prior to its discovery. [11]

    Physical characteristics

    Schumann has been characterized as a dark C-type asteroid. [3]

    Diameter and albedo

    According to the space-based surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its NEOWISE mission, Schumann's surface has an albedo of 0.04 and 0.07, and an estimated diameter of 35.0 and 38.2 kilometers, respectively. [4] [5] [6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous bodies of 0.057, and calculates a diameter of 32.0 kilometers. [3]

    Rotation period

    Several photometric lightcurves of Schumann gave a rotation period between 5.60 and 5.75 hours with a brightness amplitude in the range of 0.20 to 0.23 in magnitude ( U=3-/2+/2 ). [9] [8] [7]

    Naming

    This minor planet was named in honor of German composer of the Romantic era, Robert Schumann (1810–1856), known for his Lieder , chamber works and cello concerti. He was born in Zwickau, in proximity to the discovering observatory in Tautenburg. [2] The official naming citation was published by the Minor Planet Center on 20 May 1989 ( M.P.C. 14634). [12]
