It was discovered on 11 October 1953, by Japanese astronomer Tetsuyasu Mitani at Kyoto University's Kwasan Observatory (377), near Kyoto, Japan. It was named after the former director of the discovering observatory. Classification and orbit Ueta is a S-type asteroid, that orbits the Sun in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 4 months (1,225 days). Its orbit has an eccentricity of 0.18 and an inclination of 6° with respect to the ecliptic. It was first identified as 1926 RR at Johannesburg in 1926. Uetas observation arc begins 22 years prior to its official discovery observation with a precovery taken at Lowell Observatory in 1931. Rotation period and pole Several rotational lightcurves of Ueta were obtained from photometric observations. Best rated lightcurves were obtained by astronomers Robert Stephens and David Higgins in September 2009, securing an identical rotation period of 2.720 hours with a brightness variation of 0.35 and 0.39 magnitude, respectively (U=3/3). Modeled lightcurves from various photometric data sources also gave a similar period of 2.717943 and 2.718238 hours (U=n.a.). Diameter and albedo According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Ueta measures between 7.13 and 9.93 kilometers in diameter, and its surface has an albedo between 0.251 and 0.479. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 11.04 kilometers with an absolute magnitude of 12.15. Naming Ueta was named by the discoverer for the former Director of Kwasan Observatory (also see External links) who encouraged him to keep on with his observations of minor planets and comets. The official 1619 naming citation was published by the Minor Planet Center on 1 February 1965 (M.P.C. 2347). References 2016-09-14 last obs.
