The Leonard Euler Telescope is a 1.2-meter Swiss reflector, built at the Geneva Observatory, located at La Silla Observatory, operated by the University of Geneva, and named in honor of the famous Swiss mathematician. It is used specifically, in conjunction with the Coralie spectrograph, to conduct high-precision radial velocity measurements principally to search for large extrasolar planets in the southern celestial hemisphere. Its first success was the discovery of a planet in orbit around Gliese 86.
