Seine Planeten

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.

Woher das stammt

NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
