2732 Witt, provisional designation Шаблон:Mp, is a bright asteroid and namesake of the Witt family located in the central regions of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 19 March 1926, by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in Heidelberg, Germany. The unusual A-type asteroid was named after astronomer Carl Gustav Witt.[1][2]
Orbit and classification
Witt the parent body and namesake of the Witt family (Шаблон:Small),[3] a large family of stony asteroids with more than 1,600 known members.[4]
It orbits the Sun in the central main-belt at a distance of 2.7–2.8 AU once every 4 years and 7 months (1,675 days; semi-major axis of 2.76 AU). Its orbit has an eccentricity of 0.02 and an inclination of 6° with respect to the ecliptic.[2] The body's observation arc begins at Heidelberg in April 1926, two week after its official discovery observation.[1]
Physical characteristics
In the SMASS classification, Witt is an uncommon A-type asteroid,[2] while the overall spectral type for members of the Witt family is that of an S-type.[4]Шаблон:Rp
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Witt measures 11.001 kilometers in diameter and its surface has a high albedo of 0.305.[5]
Rotation period
As of 2018, no rotational lightcurve of Witt has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[2]
Naming
This minor planet was named by Brian G. Marsden after Carl Gustav Witt (1866–1946), a German astronomer at the Berlin Observatory and a discoverer of minor planets himself, best known for the discovery of the near-Earth asteroid 433 Eros.[1] The official naming citation was published by the Minor Planet Center on 22 September 1983 (Шаблон:Small).[6]
