“11949 Kagayayutaka”的意思、由来-开放百科全书

This minor planet was named after Kagaya Yutaka (born 1968), a Japanese space and digital artist and receiver of the Gold Medal in the American Digital Art Contest in 2000.^[2] The approved naming citation was published by the Minor Planet Center on 10 September 2003 ({{small|M.P.C. 49674}}).^[21]

Physical characteristics

Diameter and albedo

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Kagayayutaka measures 22.28 kilometers in diameter and its surface has a high albedo of 0.708,^[5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 23.21 kilometers with an absolute magnitude of 11.9.^[3]

Lightcurves

A rotational lightcurve of Kagayayutaka was obtained from photometric observations by French astronomer René Roy in November 2015. Lightcurve analysis gave a rotation period of {{val|3.96}} hours with a brightness variation of 0.28 magnitude ({{small|U=3-}}).^[7]

It was discovered on 19 September 1993, by Japanese amateur astronomers Kin Endate and Kazuro Watanabe at Kitami Observatory in eastern Hokkaidō, Japan.^[16] The asteroid was named after Japanese artist Kagaya Yutaka.^[2] Orbit and classification Kagayayutaka is a non-family asteroid from the main belt's background population. It orbits the Sun in the outer main-belt at a distance of 2.5–3.6 AU once every 5 years and 5 months (1,984 days). Its orbit has an eccentricity of 0.18 and an inclination of 8° with respect to the ecliptic. The body's observation arc starts with its official discovery observation.^[16] Naming This minor planet was named after Kagaya Yutaka (born 1968), a Japanese space and digital artist and receiver of the Gold Medal in the American Digital Art Contest in 2000.^[2] The approved naming citation was published by the Minor Planet Center on 10 September 2003 ({{small\|M.P.C. 49674}}).^[21] Physical characteristics Kagayayutaka has been characterized as a stony S-type asteroid by Pan-STARRS photometric survey.^[10] Diameter and albedo According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Kagayayutaka measures 22.28 kilometers in diameter and its surface has a high albedo of 0.708,^[5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 23.21 kilometers with an absolute magnitude of 11.9.^[3] Lightcurves A rotational lightcurve of Kagayayutaka was obtained from photometric observations by French astronomer René Roy in November 2015.
