2384 Schulhof (prov. designation:1943 EC1) is a mid-sizedasteroid and the namesake of theSchulhof family, located in the Eunomian region of the intermediateasteroid belt. It was discovered on 2 March 1943, by French astronomerMarguerite Laugier atNice Observatory in southeastern France.[1] The asteroid was later named after Hungarian astronomerLipót Schulhof.[2] The presumedS-type asteroid has a shortrotation period of 3.3 hours and measures approximately 12 kilometers (7.5 miles) in diameter.
Schulhof is the principal body and namesake of theSchulhof family, a smallasteroid family within the region of theEunomia family of the main-belt.[4][9] It orbits the Sun in thecentral asteroid belt at a distance of 2.3–2.9 AU once every 4 years and 3 months (1,541 days). Its orbit has aneccentricity of 0.12 and aninclination of 14° with respect to theecliptic.[3] It was first observed asA909 BF atHeidelberg Observatory in 1909. The body'sobservation arc begins with its official discovery observation at Nice in 1943.[1]
Thisminor planet was named in memory of Austrian–Hungarian astronomerLipót Schulhof (1847–1921), observer of asteroids and comets, discoverer of the main-belt asteroid147 Protogeneia, and awardee of theLalande Prize.[2] The official naming citation was published by theMinor Planet Center on 17 February 1984, based on a suggestion byBrian G. Marsden (M.P.C. 8541).[10]
Schulhof is an assumedS-type asteroid.[7]

In April 2002, a rotationallightcurve ofSchulhof was obtained from photometric observations at the U.S.Oakley Observatory. It gave a well-definedrotation period of3.294±0.006 hours with a brightness variation of 0.43magnitude (U=3).[8]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Schulhof measures 11.5 and 11.7 kilometers in diameter and its surface has analbedo of 0.27 and 0.28, respectively.[5][6] TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived form15 Eunomia, the family's largest member and namesake – and calculates a diameter of 12.7 kilometers with anabsolute magnitude of 11.8.[7]
