10251 Mulisch

10251 Mulisch, provisional designation 3089 T-1, is a bright background asteroid from the inner regions of the asteroid belt, approximately 2.4 kilometers (1.5 miles) in diameter. It was discovered during the Palomar–Leiden Trojan survey on 26 March 1971, by Ingrid and Cornelis van Houten at Leiden, and Tom Gehrels at Palomar Observatory in California, United States. The asteroid was named after Dutch writer Harry Mulisch.[1]

    Orbit and classification

    Mulisch is a non-family asteroid from the main belt's background population.[3] It orbits the Sun in the inner main-belt at a distance of 2.1–2.5 AU once every 3 years and 7 months (1,302 days; semi-major axis of 2.33 AU). Its orbit has an eccentricity of 0.09 and an inclination of 2° with respect to the ecliptic.[2] The body's observation arc begins at Palomar on 26 March 1971, two nights prior to its official discovery observation.[1]

    Palomar–Leiden Trojan survey

    The survey designation "T-1" stands for the first Palomar–Leiden Trojan survey, named after the fruitful collaboration of the Palomar and Leiden Observatory in the 1960s and 1970s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with the discovery of several thousand asteroid discoveries.[5]

    Physical characteristics

    The asteroid has an absolute magnitude 15.2. Based on its high albedo measured by the Wide-field Infrared Survey Explorer, Mulisch likely belongs to the stony S-complex.[2] As of 2018, no rotational lightcurve of this asteroid has been obtained from photometric observations. Its rotation period, pole and shape remain unknown.[2]

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's WISE telescope, Mulisch measures 2.398 kilometers in diameter and its surface has an albedo of 0.337.[4]

    Naming

    This minor planet was named after Dutch writer Harry Mulisch (1927–2010), known for his novels, plays, essays, poems and philosophical reflections such as The Discovery of Heaven.[1] The official naming citation was published by the Minor Planet Center on 13 June 2006 (M.P.C. 56959).[6]
