2384 Schulhof (prov. designation: Шаблон:Mp) 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 Шаблон:Convert in diameter.
Orbit and classification
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.[3][4] 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.[5] It was first observed as Шаблон:Mp at Heidelberg Observatory in 1909. The body's observation arc begins with its official discovery observation at Nice in 1943.[1]
Naming
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 (Шаблон:Small).[6]
Physical characteristics
Schulhof is an assumed S-type asteroid.[7]
Rotation period
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 Шаблон:Val hours with a brightness variation of 0.43 magnitude (Шаблон:Small).[8]
Diameter and albedo
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.[9][10] 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.[7]
