1936 Lugano, provisional designation 1973 WD, is a dark asteroid from the asteroid belt about 30 kilometers in diameter. It was discovered on November 24, 1973 by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland.[7] It orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 4 months (1,599 days)[1] and has a rotation period of nearly 20 hours.[6]
Observations of the carbonaceous Ch-type asteroid have resulted in a lower albedo and hence larger diameter than previously estimated. While in 2004, the Supplemental IRAS Minor Planet Survey (SIMPS) using data from the Infrared Astronomical Satellite, IRAS, gave a geometric albedo of 0.10 and a diameter of 25 kilometers,[3] more recent measurements by NEOWISE suggested the asteroid to be much darker, with an albedo of only 0.03 and a diameter of nearly 34 kilometers.[5]
The asteroid is named after the Swiss-Italian city of Lugano, located south of the Alps and known for its mild climate. During the winter half-year of 1973/74, Paul Wild discovered three more asteroids, 1935 Lucerna, 1937 Locarno and 1938 Lausanna, which he named after the Swiss cities Lucerne, Locarno and Lausanne, respectively, composing a quartet of sequentially numbered, thematically named asteroids.[2]
