TRAPPIST
(Transiting Planets and Planetesimals Small Telescope)
is a pair of Belgian robotic telescopes that
search for and observe extra-solar planettransits,
as well as solar systemminor planets.
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.
Among their discoveries are exoplanets around the starTRAPPIST-1
including more than one in its habitable zone.
