The Leonhard Euler Telescope and Swiss 1.2-meter Leonhard Euler Telescope , or shortly Euler telescope is a reflecting telescope with 1.2 m aperture of the Observatory of Geneva at the La Silla Observatory of the European Southern Observatory in Chile .

The telescope is since its completion in the year 1998 by the Swiss University of Geneva operated. It was named after the mathematician Leonhard Euler .

Together with the Belgian Mercator telescope from the Katholieke Universiteit Leuven , both telescopes were part of the Southern Sky Extrasolar Planet Search Program , which was able to discover numerous extrasolar planets.

The CORALIE Echelle spectrograph was used especially for this . The first planet was the one of those in orbit of Gliese 86th , a planet of about 4 Jupiter masses and an orbital period of about 15.8 days . After that, several other extrasolar planets were either discovered or studied with this telescope.
