1038 Tuckia, provisional designation1924 TK, is rare-typeHilda asteroid from the outermost regions of theasteroid belt, approximately 58 kilometers in diameter. It was discovered on 24 November 1924, by German astronomer byMax Wolf atHeidelberg Observatory in southwest Germany.[3] The asteroid was named after American bankerEdward Tuck and his wife.[2]
Tuckia is a member of theHilda family (001), anasteroid family within the dynamicalHilda group, an orbital group of asteroids in theoutermost main-belt, that stay in a 3:2orbital resonance with the gas giantJupiter. This means that the asteroid makes 3 orbits for every 2 orbits Jupiter makes.[3]
It orbits the Sun at a distance of 3.1–4.9 AU once every 7 years and 11 months (2,902 days). Its orbit has aneccentricity of 0.22 and aninclination of 9° with respect to theecliptic.[1] The asteroids'sobservation arc begins with its official discovery observation at Heidelberg.[3]
In theTholen classification,Tuckia is a rare DTU:-type, a subtype of the darkD-type asteroids.[1]
In the 1990s, a rotationallightcurve ofTuckia was obtained from photometric observations by Swedish astronomer Dahlgren and colleges during a survey of Hildian asteroids. Lightcurve analysis gave a somewhat longer than averagerotation period of 23.2 hours with a brightness amplitude of 0.1magnitude (U=2).[6]
According to the survey carried out by the JapaneseAkari satellite,Tuckia measures 52.69 kilometers in diameter and its surface has analbedo of 0.030,[5] while the Collaborative Asteroid Lightcurve Link derives an albedo of 0.0304 and a diameter of 58.36 kilometers based on anabsolute magnitude of 10.82.[4]
Thisminor planet was named after American banker and philanthropistEdward Tuck (1842–1938) and his wife. He is the son ofAmos Tuck who was a founder of the Republican Party in the United States. The name was suggested by G. Camille Flammarion. The official naming citation was published byPaul Herget inThe Names of the Minor Planets in 1955 (H 99).[2]
