Hans-Emil Schuster (born 19 September 1934 inHamburg) is a Germanastronomer and a discoverer ofminor planets andcomets, who retired in October 1991. He worked atHamburg Observatory atBergedorf andEuropean Southern Observatory (ESO), and was a former acting director ofLa Silla Observatory. From 1982, he was married to Rosemarie Schuster née von Holt (28 March 1935 – 18 September 2006)

He discovered periodiccomet106P/Schuster. He also discovered the cometC/1976 D2 (in the contemporary nomenclature, it was known as Comet 1975 II or 1976c), which was notable for its largeperihelion distance of 6.88AU[1][2], the largest yet observed at the time.

He discovered 25asteroids, including notably theApollo asteroid2329 Orthos and theAmor asteroids2608 Seneca,3271 Ul,3288 Seleucus, and3908 Nyx. He discovered thenear-Earth asteroid161989 Cacus, which was lost and not recovered until 2003.

Schuster participated in the exploration, selection and testing of the sites of two ESO observatories: La Silla Observatory andParanal Observatory (the latter is theVLT site).

He also participated in two ESO Southern Sky Surveys: the ESO-B survey ("Quick-Blue Survey") completed in 1978 was the first deep optical survey of the southern sky, and the "Red Sky Survey". Photographic plates were taken with the ESO's 1-meter Schmidt Telescope at La Silla.

He co-discovered thePhoenix Dwarf galaxy (withRichard M. West), and in 1976 also discovered theEridanus Globular Cluster, one of the most distantglobular clusters in thegalactic halo. In 1980, he discovered a type-IIsupernova in thegalaxyNGC 1255. However, "Schuster's Spiral" (Horologium Dwarf) is not named after him, but a different Schuster.

Theasteroid2018 Schuster was named in his honour. On 21 October 2011, he was awarded the rank of Commander of theOrder of Bernardo O'Higgins in recognition of his important contribution to astronomy in Chile.
