1690 Mayrhofer, provisional designation 1948 VB, is a dark asteroid from the outer region of the asteroid belt, about 32 kilometers in diameter. It was discovered by French female astronomer Marguerite Laugier at Nice Observatory in south-east France on 8 November 1948.[10]
The asteroid orbits the Sun at a distance of 2.7–3.3 AU once every 5.29 years (1,934 days). Its orbit shows an eccentricity of 0.10 and is tilted by 13 degrees to the plane of the ecliptic. It takes between 19 and 22 hours to rotate once around its axis.[8][9] The C-type asteroid has a geometric albedo of 0.06–0.08 according to surveys carried out by the IRAS, Akari, WISE and NEOWISE missions.[4][5][6][7]
Proposed by German catholic priest and amateur astronomer Otto Kippes, the asteroid was named after Austrian amateur astronomer Karl Mayrhofer (1903–1982). He lived in the Austrian town of Ried im Innkreis and was known for his calculations of orbital elements for asteroids.[2]
