(ground-based automatic transiting planet finding telescope)

TRAPPIST (Transiting Planets and Planetesimals Small Telescope) is a pair of Belgian robotic telescopes. The original TRAPPIST telescope (TRAPPIST-South), with a 0.6-meter aperture has been operating since 2010 at La Silla Observatory (LSO) in Chile, using the housing of the retired Swiss T70 Telescope. A second, identical telescope (TRAPPIST-North), operating since 2016 is at Oukaïmeden Observatory in Morocco. They search for and observes extra-solar planet transits, as well as solar system planetesimals. Among their discoveries are exoplanets around the star TRAPPIST-1 including more than one in its habitable zone.
