1700 Zvezdara, provisional designation1940 QC, is a darkasteroid from the inner regions of theasteroid belt, approximately 21 kilometers in diameter. It was discovered on 27 August 1940, by Serbian astronomerPetar Đurković atBelgrade Astronomical Observatory, Serbia, and named after theZvezdara hill in Belgrade.[2][9]
The asteroid orbits the Sun in theinner main-belt at a distance of 1.8–2.9 AU once every 3 years and 8 months (1,325 days). Its orbit has aneccentricity of 0.23 and aninclination of 5° with respect to theecliptic.[1] It was first identified as1929 PM atJohannesburg Observatory in 1929, extending the body's observation arc by 11 years prior to its official discovery observation at Belgrade.[9]
Zvezdara is characterized as anX-type asteroid in theTholen classification.[1]
In September 2009, two rotationallightcurves ofZvezdara were obtained from observations, after being identified as a good candidate forphotometry.[10] They gave an identicalrotation period of 9.114 hours with a brightness variation of 0.10 and 0.13magnitude, respectively (U=3/3-).[6][a]
According to the survey carried out by the JapaneseAkari satellite and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Zvezdara measures 20.17 and 21.71 kilometers in diameter and its surface has analbedo of 0.045 and 0.039, respectively.[4][5] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.043 and a diameter of 20.86 kilometers based on anabsolute magnitude of 12.45,[3] similar to one of the lightcurve studies that calculated a diameter of 20.89 kilometers.[6][verification needed]
Thisminor planet is named after the hillyZvezdara municipality of the city of Belgrade. It is the location of the Belgrade Observatory, founded in 1934.[2] The Serbian wordZvezdara means "star-house" when literally translated.Zvezdara was one of two asteroids discovered by Petar Đurković, the other being1605 Milankovitch. The official naming citation was published by theMinor Planet Center on 1 August 1980 (M.P.C. 5449).[11]
