An ultra-cool red dwarf star about 40 light-years away that hosts seven known terrestrial planets.
The TRAPPIST-1 system is a planetary system with 7 known planets in this catalogue.
Detecting the tiny dip in a star's brightness as a planet passes in front of it.
The NASA Exoplanet Archive is the authoritative catalogue of confirmed exoplanets and their measured parameters.
The habitable zone is the range of orbits around a star where a planet could, in principle, hold liquid water on its surface. Lying in the zone is not a guarantee of habitability.
