1960 Guisan, provisional designation 1973 UA, is a carbonaceous asteroid from the middle region of the asteroid belt, approximately 25 kilometers in diameter.
It was discovered on 25 October 1973, by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, and named after Swiss General Henri Guisan.




Orbit and classification


Guisan orbits the Sun in the central main-belt at a distance of 2.2–2.8 AU once every 4.02 years (1,467 days). Its orbit has an eccentricity of 0.12 and an inclination of 8° with respect to the ecliptic.




Physical characteristics


Guisan has been characterized as a dark C-type asteroid.
It has a rotation period of 8.46 hours and a geometric albedo of 0.04–0.05, as measured by the IRAS, Akari, WISE and NEOWISE surveys.




Naming


This minor planet 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. The official naming citation was published by the Minor Planet Center on 18 April 1977 (M.P.C. 4157).
