    1544 Vinterhansenia, provisional designation 1941 UK, is a carbonaceous asteroid from the inner regions of the asteroid belt, about 23 kilometers in diameter. It was discovered by Finnish female astronomer Liisi Oterma at Turku Observatory, Southwest Finland, on 15 October 1941.[9]

    The C-type asteroid orbits the Sun at a distance of 2.1–2.6 AU once every 3 years and 8 months (1,335 days). Its orbit shows an eccentricity of 0.10 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of 13.7 hours[7][8] and an albedo between 0.04 and 0.08, according to the surveys carried out by the Infrared Astronomical Satellite, IRAS, and the Wide-field Infrared Survey Explorer.[4][5][6]

    The minor planet was named after Danish female astronomer Julie Vinter Hansen (1890–1960), who worked at the Copenhagen Observatory and was director of the International Astronomical Union's telegram bureau and Editor of its Circulars (also see Central Bureau for Astronomical Telegrams)[2]
