2058 Róka, provisional designation 1938 BH, is a Themistian asteroid from the outer regions of the asteroid belt, approximately 22 kilometers in diameter.
It was discovered on 22 January 1938, by Hungarian György Kulin at Konkoly Observatory in Budapest, Hungary.[11] The asteroid was named in memory of Hungarian science writer Gedeon Róka.[2]
Classification and orbit
Róka is a member of the Themis family, a dynamical family of carbonaceous outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun at a distance of 2.7–3.6 AU once every 5 years and 6 months (2,016 days). Its orbit has an eccentricity of 0.15 and an inclination of 3° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Konkoly in 1938.[11]
Physical characteristics
Róka has been characterized as a carbonaceous C-type asteroid by Pan-STARRS photometric survey.[10] Due to its ambivalent albedo it is also an assumed S-type asteroid.[3]
