6546 Kaye
6546 Kaye ("prov. designation": ) is a dark and elongated background asteroid from the outer region of the asteroid belt. It was discovered on 24 February 1987, by Czech astronomer Antonín Mrkos at the South Bohemian Kleť Observatory in the Czech Republic. The presumed C-type asteroid has a rotation period of 10.0 hours and measures approximately in diameter. It was named for American actor Danny Kaye. Orbit and classification. When applying the synthetic hierarchical clustering method (HCM) by Nesvorný, or the 1995 HCM-analysis by Zappalà, "Kaye" is a non-family asteroid of the main belt's background  population, while according to another HCM-analysis by Milani and Knežević (AstDyS), it is a core member of the Ursula family (), a family of 1,500 asteroids with a C- and X-type. It orbits the Sun in the outer main-belt at a distance of 2.9–3.6 AU once every 5 years and 9 months (2,113 days). Its orbit has an eccentricity of 0.11 and an inclination of 14° with respect to the ecliptic. It was first observed as at Crimea–Nauchnij in 1978, extending the body's observation arc by 9 years prior to its official discovery observation at  Kleť Observatory. Naming. This minor planet was named in memory of American actor and singer David Daniel Kaminsky (1911–1987), known by his screen name as "Danny Kaye". Kaye starred in popular feature films such as "The Court Jester" (1956), typically playing the role of a gentle bumbler who triumphs eventually. The minor planet's name was suggested by G. V. Williams, who made the identifications for this body. The was published by the Minor Planet Center on 20 June 1997 (). Physical characteristics. Rotation period. In August 2012, two rotational lightcurves of "Kaye" were obtained from photometric observations at the Palomar  Transient Factory in California. Lightcurve analysis gave a rotation period of and hours with a brightness variation of 0.32 and 0.34 magnitude in the R and S-band, respectively (). Diameter and albedo. According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Kaye" measures between 21.6 and 23.8 kilometers in diameter and its surface has an albedo between 0.065 and 0.085. The "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 23.2 kilometers with an absolute magnitude of 11.9. 6546 Kaye 6546
