2384 Schulhof ( prov. designation: 1943 EC1) is a mid-sized asteroid and the namesake of the Schulhof family, located in the Eunomian region of the intermediate asteroid belt. It was discovered on 2 March 1943, by French astronomer Marguerite Laugier at Nice Observatory in southeastern France. [1] The asteroid was later named after Hungarian astronomer Lipót Schulhof. [2] The presumed S-type asteroid has a short rotation period of 3.3 hours and measures approximately 12 kilometers (7.5 miles) in diameter.
Schulhof is the principal body and namesake of the Schulhof family, a small asteroid family within the region of the Eunomia family of the main-belt. [4] [9] It orbits the Sun in the central asteroid belt at a distance of 2.3–2.9 AU once every 4 years and 3 months (1,541 days). Its orbit has an eccentricity of 0.12 and an inclination of 14 ° with respect to the ecliptic. [3] It was first observed as A909 BF at Heidelberg Observatory in 1909. The body's observation arc begins with its official discovery observation at Nice in 1943. [1]
This minor planet was named in memory of Austrian–Hungarian astronomer Lipót Schulhof (1847–1921), observer of asteroids and comets, discoverer of the main-belt asteroid 147 Protogeneia, and awardee of the Lalande Prize. [2] The official naming citation was published by the Minor Planet Center on 17 February 1984, based on a suggestion by Brian G. Marsden ( M.P.C. 8541). [10]
Schulhof is an assumed S-type asteroid. [7]
In April 2002, a rotational lightcurve of Schulhof was obtained from photometric observations at the U.S. Oakley Observatory. It gave a well-defined rotation period of 3.294±0.006 hours with a brightness variation of 0.43 magnitude ( U=3). [8]
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Schulhof measures 11.5 and 11.7 kilometers in diameter and its surface has an albedo of 0.27 and 0.28, respectively. [5] [6] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived form 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 12.7 kilometers with an absolute magnitude of 11.8.
