Johann Franz Encke (German pronunciation: [ˈjoːhan ˈfʁants ˈɛŋkə]; 23 September 1791 – 26 August 1865) was a German astronomer. Among his activities, he worked on the calculation of the periods of comets and asteroids, measured the distance from the Earth to the Sun, and made observations of the planet Saturn.

Johann Franz Encke (born Sept. 23, 1791, Hamburg—died Aug. 26, 1865, Spandau, Ger.) was a German astronomer who in 1819 established the period of the comet now known by his name ( see Encke’s Comet ). Encke was educated at Hamburg and the University of Göttingen, where he worked under the direction of Carl Friedrich Gauss.

Mar 31, 2004 · That was some five years before German mathematician Johann Franz Encke was born! The comet was “discovered” again in 1795, 1805, and 1818, and during the last of these returns Encke himself observed it. His calculation of the comet’s orbit led him to recognize that it was the very same object already seen in 1786, 1795, and 1805.
Johann Franz Encke. 1791-1865. German astronomer known for his mathematical work in astronomy, especially on short periodic comets. Following the discovery of a comet with a very short orbiting period around the Sun (3.3 years), Encke developed (in 1819) the mathematical formulae needed to calculate the orbits of this and other short periodic ...
Johann Encke was the leading German astronomer of his generation, contributing substantially to celestial mechanics, observation of the Solar System, and the professional development of the German‐speaking astronomical community. He was the son of Johann Michael Encke and Marie Misler.
