6546 Kaye, provisional designation 1987 DY4, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 22 kilometers in diameter. It was discovered on 24 February 1987, by Czech astronomer Antonín Mrkos at the South Bohemian Kleť Observatory in the Czech Republic.[8] The asteroid was named for American actor Danny Kaye.[2]

Orbit and classification[edit]

Kaye 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.[1] It was first identified as 1978 RF2 at Crimea–Nauchnij in 1978, extending the body's observation arc by 9 years prior to its official discovery observation at Klet Observatory.[8]

Physical characteristics[edit]

Rotation period[edit]

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 10.0059 and 10.0186 hours with a brightness variation of 0.32 and 0.34 magnitude in the R and S-band, respectively (U=2/2).[3][6]

Diameter and albedo[edit]

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.[4][5]

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.[3]


This minor planet was named in memory of American actor and singer David Daniel Kaminsky (1913–1987), known by his screen name as "Danny Kaye".[2]

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.[2] The approved naming citation was published by the Minor Planet Center on 20 June 1997 (M.P.C. 30099).[9]
