Primo pianeta scoperto nel 2016 con il transito (NASA Exoplanet Archive).

I suoi pianeti

TRAPPIST-1 b — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 36 hours; about 130 °C, hotter than boiling water; found in 2016 by transit.
TRAPPIST-1 c — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 2 days; about 67 °C, between freezing and boiling; found in 2016 by transit.
TRAPPIST-1 d — 0.8 times Earth's width, smaller than the Earth; its year lasts 4 days; about 13 °C, between freezing and boiling; found in 2016 by transit.
TRAPPIST-1 e — 0.9 times Earth's width, about Earth-sized — probably rocky; its year lasts 6 days; about −23 °C, below freezing; found in 2017 by transit.
TRAPPIST-1 f — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 9 days; about −55 °C, below freezing; found in 2017 by transit.
TRAPPIST-1 g — 1.1 times Earth's width, about Earth-sized — probably rocky; its year lasts 12 days; about −76 °C, below freezing; found in 2017 by transit.
TRAPPIST-1 h — 0.8 times Earth's width, smaller than the Earth; its year lasts 19 days; about −100 °C, below freezing; found in 2017 by transit.
