1856 Růžena, provisional designation 1969 TW1, is a stony asteroid from the inner regions of the asteroid belt, approximately 6.6 kilometers in diameter. It was discovered on 8 October 1969, by Russian astronomer Lyudmila Chernykh at Crimean Astrophysical Observatory in Nauchny, on the Crimean peninsula.[4] The asteroid was named after Růžena Petrovicova, staff member at Kleť Observatory.[2]
Orbit and classification[edit]
Růžena orbits the Sun in the inner main-belt at a distance of 2.1–2.4 AU once every 3 years and 4 months (1,222 days). Its orbit has an eccentricity of 0.08 and an inclination of 5° with respect to the ecliptic.[1] The asteroid was first identified as 1941 FP at the Finnish Iso-Heikkilä Observatory. The body's observation arc, however, starts with its official discovery observation at Nauchnyj in 1969.[4]
Physical characteristics[edit]
Růžena is bright S-type asteroid in the SMASS classification.[1]
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Růžena measures 6.62 kilometers in diameter and its surface has an albedo of 0.335.[3] As of 2016, the body's rotation period and shape remain unknown.[1][5]
Naming[edit]
This asteroid was named in honor of Růžena Petrovicova, observer of comets and minor planets and staff member of the Kleť Observatory, located in what is now the Czech Republic.[2] The official naming citation was published by the Minor Planet Center on 1 June 1975 (M.P.C. 3825).[6]
