1439 Vogtia, provisional designation1937 TE, is a dark Hildianasteroid from the outermost region of theasteroid belt, approximately 48 kilometers in diameter. It was discovered on 11 October 1937, by German astronomerKarl Reinmuth atHeidelberg Observatory in southern Germany.[9] It is named for astronomerHeinrich Vogt.[2]
Vogtia is a member of theHilda family, a large group of asteroids in anorbital resonance with the gas giant Jupiter, and thought to have originated from theKuiper belt. It orbits the Sun at a distance of 3.5–4.5 AU once every 8.01 years (2,925 days). Its orbit has aneccentricity of 0.12 and aninclination of 4° with respect to theecliptic.[1] Itsobservation arc begins at Heidelberg, 15 days after its official discovery observation, with noprecoveries taken, and no prior identifications made.[9]
In the 1990s, a rotationallight-curve ofVogtia was obtained during a survey of Hilda asteroids at Swedish, German and Italian observatories. It gave a well-definedrotation period of 12.95 hours with a brightness variation of 0.33magnitude (U=3).[7] In October 2016, American astronomerBrian D. Warner obtained another light-curve at his Palmer Divide Station/CS3 in Colorado, which gave a period of 12.898 hours and an identical amplitude of 0.33 magnitude (U=3).[a][b]
In theTholen taxonomy,Vogtia is classified as a rareXFU-type, while it is also described as aC/P-type asteroid.[5] According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Vogtia measures between 47.87 and 52.86 kilometers in diameter, and its surface has a lowalbedo between 0.043 and 0.051.[4][5][6] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.0425 and a diameter of 47.79 kilometers based on an absolute magnitude of 10.65.[3]
Thisminor planet was named forHeinrich Vogt (1890–1968), German astronomer atUniversity of Heidelberg.[2] He discovered the main-belt asteroid735 Marghanna in 1912, and was a known member of the Nazi paramilitarySturmabteilung.[10]
