}}2156 Kate, provisional designation {{mp|A917 SH}}, is a stony, rare-type asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. The asteroid was discovered on 23 September 1917, by Soviet–Russian astronomer Sergey Belyavsky at Simeiz Observatory on the Crimean peninsula.[22] It was named for Kate Kristensen, wife of astronomer L. K. Kristensen.[2]

Orbit and classification

Kate orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,226 days). Its orbit has an eccentricity of 0.20 and an inclination of 5° with respect to the ecliptic. As no precoveries were taken, and no prior identifications were made, the asteroid's observation arc begins with its official discovery observation at Simeiz in 1917.[22]

Physical characteristics

In the Tholen classification, Kate is a common S-type asteroid. It has also been characterized as a rare A-type asteroid by Pan-STARRS{{'}} large photometric survey.[14]

Rotation period

A large number of rotational lightcurves were obtained from photometric observations. They gave a well-defined rotation period of 5.620 to 5.623 hours with a brightness variation between 0.5 and 0.9 magnitude ({{small|U=3/3-}}).[7][8][9]{{efn|name=lcdb-Dunckel}}

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Kate measures 8.131 kilometers in diameter and its surface has an albedo of 0.189 and 0.2242, respectively,[4][5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 8.61 kilometers with an absolute magnitude of 12.69.[6]

Naming

This minor planet was named after Kate Kristensen, wife of astronomer L. K. Kristensen, who was involved in the body's orbit computation.[2] The official naming citation was published by the Minor Planet Center on 1 April 1980 ({{small|M.P.C. 5284}}).[35]
