Bobhope is a member of the Meliboea family, a smaller asteroid family of carbonaceous outer-belt asteroids with a few hundred members, named after 137 Meliboea.:23 It orbits the Sun in the outer main-belt at a distance of 2.5–3.7 AU once every 5 years and 5 months (1,985 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 lightcurve of Bobhope 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 5.013±0.003 hours with a brightness variation of 0.46±0.08magnitude (U=2). A previously published lightcurve by French amateur astronomer Bernard Christophe gave a somewhat longer period of 6.0888±0.0007 hours with an amplitude of 0.50 (U=2).
More dated NEOWISE publications gave a larger diameter of 41.361 and 44.8 kilometers, respectively. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0586 and a diameter of 38.0 kilometers with an absolute magnitude of 10.8.
This 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. Hope also received more than forty honorary doctorates. The official naming citation was published by the Minor Planet Center on 1 September 1993 (M.P.C. 22496).
