2732 Witt
From Wikipedia, the free encyclopedia
Witt the parent body and namesake of the Witt family (535),[3] a large family of stony asteroids with more than 1,600 known members.[5]
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.[5]: 23
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.[4]
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]
