    1619 Ueta, provisional designation 1953 TA, is a stony asteroid from the inner regions of the asteroid belt, about 11 kilometers in diameter. It was discovered by Japanese astronomer Tetsuyasu Mitani at Kyoto University's Kwasan Observatory on 11 October 1953.[11]

    The S-type asteroid orbits the Sun at a distance of 1.8–2.6 AU once every 3 years and 4 months (1,226 days). Its orbit shows an eccentricity of 0.18 and is tilted by 6 degrees to the plane of the ecliptic. It has a rotation period of 2.7 hours and an albedo around 0.25,[4] with a divergent result of 0.5.[5]

    It was named by the discoverer after the former Director of Kwasan Observatory (also see § External links) who encouraged him to keep on with his observations of asteroids and comets.[2]
