1439 Vogtia, provisional designation 1937 TE, is a dark Hildian asteroid from the outermost region of the asteroid belt, approximately 48 kilometers in diameter. It was discovered on 11 October 1937, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany.[9] It is named for astronomer Heinrich Vogt.[2]

Description

Vogtia is a member of the Hilda family, a large group of asteroids in an orbital resonance with the gas giant Jupiter, and thought to have originated from the Kuiper 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 an eccentricity of 0.12 and an inclination of 4° with respect to the ecliptic.[1] Its observation arc begins at Heidelberg, 15 days after its official discovery observation, with no precoveries taken, and no prior identifications made.[9]

In the 1990s, a rotational light-curve of Vogtia was obtained during a survey of Hilda asteroids at Swedish, German and Italian observatories. It gave a well-defined rotation period of 12.95 hours with a brightness variation of 0.33 magnitude ({{{1}}}).[7] In October 2016, American astronomer Brian 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 ({{{1}}}).[lower-alpha 1][lower-alpha 2]


This minor planet was named for Heinrich Vogt (1890–1968), German astronomer at University of Heidelberg.[2] He discovered the main-belt asteroid 735 Marghanna in 1912, and was a known member of the Nazi paramilitary Sturmabteilung.[10]
