The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) is a Belgian, remote and robotic telescope in Chile, which came online in 2010. It is named in homage to Trappists in the Belgian region.[1][2]
Situated high in the Chilean mountains at ESO's La Silla Observatory, it is actually controlled from Liege, Belgium with some autonomous features. It is a reflecting telescope 0.60 m (23.5″) in aperture diameter and is housed in the dome of the retired Swiss T70 telescope.
The telescope is a joint venture between the University of Liège, Belgium and Geneva Observatory, Switzerland, and among other tasks, it specializes in comets and hunting exoplanets.[3][4]
In November 2010, it was one of the few telescopes that observed a stellar occultation of the planetary body Eris, revealing that it may be smaller than Pluto, and it helped observe a stellar occultation by Makemake, when it passed in front of the star NOMAD 1181-0235723. The observations of this event showed it lacked a significant atmosphere.[5][4]
