1879 Broederstroom
1879 Broederstroom, provisional designation 1935 UN, is a stony asteroid from the inner regions of the asteroid belt. It was discovered by Dutch astronomer Hendrik van Gent at the Leiden Southern Station, annex to the Johannesburg Observatory in South Africa on 16 October 1935.〔
The S-type asteroid is a member of the Flora family and measures approximately 7 kilometers in diameter. It orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,229 days). Its orbit show an eccentricity of 0.15 and is nearly coplaner to the ecliptic, inclined by only 1.7 degrees.〔 It has an albedo of 0.24 and 0.32, as measured by the WISE/NEOWISE and Akari surveys, respectively.〔〔
Photometric light-curve observations made by Italian amateur astronomer Antonio Vagnozzi〔 and the U.S. Palomar Transient Factory Survey gave a rotation period of 3.02 hours.〔〔
The asteroid was named after the village Broederstroom located in the North West province of South Africa. The Leiden Southern Observatory was later located near this town for 25 years until 1982.〔
