2064 Thomsen

The S-type asteroid orbits the Sun in the inner main-belt at a distance of 1.5–2.9 AU once every 3 years and 3 months (1,174 days). Its orbit has an eccentricity of 0.33 and an inclination of 6° with respect to the ecliptic. == Naming ==

This minor planet was named in memory of New Zealand astronomer Ivan Leslie Thomsen (1910–1969), director of the Carter Observatory, Wellington, from 1945 until he was appointed director of the Mount John University Observatory only two months before his death. He was an enthusiastic coordinator of New Zealand's astronomy and his efforts eventually led to the minor-planet observing program with the Carter Observatory 41-cm reflector. It was the 1977 rediscovery at the Carter Observatory that allowed this minor planet to be numbered. The official was published by the Minor Planet Center on 1 August 1978 (). == Physical characteristics ==

Four rotational lightcurves gave a well-defined rotation period of 4.233 hours with a brightness variation of 0.62–0.69 magnitude () and an albedo of 0.055 and 0.16, as measured by the IRAS and Akari surveys, respectively. == References ==
