10251 Mulisch, provisional designation3089 T-1, is a bright backgroundasteroid from the inner regions of theasteroid belt, approximately 2.4 kilometers (1.5 miles) in diameter. It was discovered during thePalomar–Leiden Trojan survey on 26 March 1971, byIngrid andCornelis van Houten at Leiden, andTom Gehrels atPalomar Observatory in California, United States. The asteroid was named after Dutch writerHarry Mulisch.[1]
Mulisch is a non-family asteroid from the main belt'sbackground population.[3] It orbits the Sun in theinner 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 aneccentricity of 0.09 and aninclination of 2° with respect to theecliptic.[2] The body'sobservation arc begins at Palomar on 26 March 1971, two nights prior to its official discovery observation.[1]
Thesurvey designation "T-1" stands for the firstPalomar–Leiden Trojan survey, named after the fruitful collaboration of the Palomar andLeiden Observatory in the 1960s and 1970s. Gehrels used Palomar'sSamuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped thephotographic plates to Ingrid and Cornelis van Houten at Leiden Observatory whereastrometry was carried out. The trio are credited with the discovery ofseveral thousand asteroid discoveries.[5]
The asteroid has anabsolute magnitude 15.2. Based on its highalbedo measured by theWide-field Infrared Survey Explorer,Mulisch likely belongs to the stonyS-complex.[2] As of 2018, no rotationallightcurve of this asteroid has been obtained fromphotometric observations. Itsrotation period,pole and shape remain unknown.[2]
According to the survey carried out by theNEOWISE mission of NASA's WISE telescope,Mulisch measures 2.398 kilometers in diameter and its surface has analbedo of 0.337.[4]
Thisminor planet was named after Dutch writerHarry Mulisch (1927–2010), known for his novels, plays, essays, poems and philosophical reflections such asThe Discovery of Heaven.[1] The official naming citation was published by theMinor Planet Center on 13 June 2006 (M.P.C. 56959).[6]
