1960 Guisan, provisional designation 1973 UA, is a dark, carbonaceous asteroid from the inner regions of the asteroid belt, about 25 kilometers in diameter. It was discovered by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland on 25 October 1973.[9]
The C-type asteroid orbits the Sun at a distance of 2.2–2.8 AU once every 4 years (1,468 days). It has a rotation period of 8.46 hours[8] and a geometric albedo of 0.04–0.05, as measured by the IRAS, Akari, WISE and NEOWISE surveys.[4][5][6][7]
It was named in memory of Henri Guisan (1874–1960), general of the Swiss army during the Second World War. He was notably from the country's smaller Swiss-French part rather than from the German-speaking part.[2]
