3567 Alvema, provisional designation 1930 VD, is a dark asteroid from the outer region of the asteroid belt, about 14 kilometers in diameter. It was discovered by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle, on 15 November 1930.[7]
The X-type asteroid orbits the Sun at a distance of 1.9–3.7 AU once every 4 years and 8 months (1,702 days). Its orbit shows an eccentricity of 0.31 and is tilted by 7 degrees to the plane of the ecliptic. Two different light-curve analysis rendered a rotation period of 8.1 hours.[5][6] It has a low albedo of 0.05, according to the survey carried out by the Wide-field Infrared Survey Explorer and its subsequent NEOWISE mission.[4]
The minor planet was named by the discoverer after Aline, Vérionique and Martine (Al-Ve-Ma), his three great-granddaughters, Aline De Middlelaer, and Vérionique and Martine Wark.[2]
