Leonhard Euler Telescope, or Swiss 1.2-m Leonhard Euler Telescope, is a 1.2-metre (3.9 ft) diameter aperture reflecting telescope at the Geneva Observatory at La Silla Observatory. It is use for astronomy, and runs the CORALIE echelle spectrograph to search for planets.[1] Its first planet discovery was of one in orbit around Gliese 86.[1] It was determined to be a 4MJ planet with an orbital period of 15.8 earth days.[2] In addition, many other extra solar-system planets were discovered or examined after this discovery.[3]
The observatory is operated by the University of Geneva of Switzerland since the telescopes was finished in 1998.[4] The telescope is named for famous mathematician Leonhard Paul Euler.[5]
The Euler 1.2 and the Mercator Telescope were part of the Southern Sky extrasolar Planet search Programme which has discovered numerous extrasolar planets.[6]
