(red dwarf with exoplanet near the habitable zone)
TRAPPIST-1 (2MASS J23062928-0502285)
is a nearby red dwarf with seven known orbiting
extra-solar planets, ranging from about 1/3 Earth
mass to just above Earth mass,
with possibly as many as six of them within
the star's presumed habitable zone,
which has encouraged much interest.
They were discovered by the TRAPPIST
observatory, which explains its designation.
