2829 Bobhope, provisional designation 1948 PK, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 40 kilometers in diameter. It was discovered on 9 August 1948, by South African astronomer Ernest Leonard Johnson at Union Observatory in Johannesburg.
The C-type asteroid is a member of the Meliboea family. It orbits the Sun at a distance of 2.5–3.7 AU once every 5 years and 5 months (1,983 days). Its orbit has an eccentricity of 0.19 and an inclination of 14° with respect to the ecliptic. It was first observed as 1942 JH at the discovering observatory in May 1942, yet the astrometric data from this observation remained unused to extend its observation arc prior to the official discovery date.
A rotational light-curve for this asteroid was obtained from photometric observations by astronomer Landy Carbo at Oakley Southern Sky Observatory (E09), Australia, and at the U.S. Oakley Observatory in September 2008. It gave it a rotation period of 7000501300000000000♠5.013±0.003 hours with a brightness variation of 6999460000000000000♠0.46±0.08 magnitude (U=2). A previously published light-curve by Raoul Behrend gave a somewhat longer period of 7000608880000000000♠6.0888±0.0007 hours with an amplitude of 0.50 (U=2).
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 38.2 and 44.8 kilometers in diameter and its surface has an albedo between 0.055 and 0.092. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0586 and a diameter of 38.0 kilometers, based on an absolute magnitude of 10.8.
The minor planet was named for English-born, American comedian Bob Hope (1903–2003), star of innumerable feature film, theater, TV and radio productions, and known for the horror comedy Cat and the Canary (1939). He hosted the Academy Awards more than any other host, and received several Honorary and Special Oscars himself. He also received more than forty honorary doctorates. Naming citation was published on 1 September 1993 (M.P.C. 22496).
