1700 Zvezdara, provisional designation 1940 QC, is a dark asteroid from the inner regions of the asteroid belt, about 21 kilometers in diameter. It was discovered by Serbian astronomer Petar Đurković at Belgrade Astronomical Observatory on 27 August 1940.[7]
The X-type asteroid orbits the Sun at a distance of 1.8–2.9 AU once every 3 years and 8 months (1,324 days). It has a rotation period of 9.114 hours.[6][lower-alpha 1] and an albedo of 0.04.[4][5] Its orbit shows an eccentricity of 0.23 and is tilted by 5 degrees to the plane of the ecliptic.[1]
After being identified in a 2009 paper as a good candidate for lightcurve photometry analysis,[8] observations were taken and results published in 2010. The study calculated that the diameter of this object is 20.89 km.[6]
The asteroid is named after the hilly Zvezdara municipality of the city of Belgrade. It is the location of the Belgrade Observatory, founded in 1934.[2] The Serbian word Zvezdara means "star-house" when literally translated.
Zvezdara was one of two asteroids discovered by Petar Đurković, the other being 1605 Milankovitch.
