Earth's equilibrium temperature is 255 K; [14][better source needed] it is Earth's greenhouse gases that raise its surface temperatures to the levels we experience. If TRAPPIST-1e has a …

Jul 28, 2025 · With its determined radius and mass, scientists have calculated Trappist-1e’s density to be around 4.885 grams per cubic centimeter, suggesting a solid, rocky composition. …

Omitted semi-major axis, irradiation, equilibrium temperature, ratio of distance to stellar radius (ranges of discrete values given for set of possible periods).

Feb 22, 2024 · The surface temperature of TRAPPIST-1e is estimated to be around -60°C (-76°F) to 10°C (50°F). This temperature range places it within conditions that could potentially …

Jul 7, 2025 · TRAPPIST-1 e is a terrestrial exoplanet that orbits an M-type star. Its mass is 0.692 Earths, it takes 6.1 days to complete one orbit of its star, and is 0.02925 AU from its star.

TRAPPIST-1e’s higher density implies an Earth-like composition and a solid rocky surface. TRAPPIST-1e has 93 percent of Earth’s surface gravity, the system’s second-highest. Given …

Prior conclusions regarding the habitability of TRAPPIST-1f are now changed. While TRAPPIST-1f with 1 bar CO2 still enters a fully glaciated state, the planet can maintain a global mean …

Its equilibrium temperature ranges from 225 K (-48 °C; -55 °F) to 246.1 K (-27.1 °C; -16.7 °F), depending on how much light the planet reflects into space. Both of these are between those …

The seven planets have equilibrium temperatures low enough to support liquid water on their surfaces. This table lists all stars in the system TRAPPIST-1. The following plot shows the …

Above is an artist's impression of Trappist-1e. Trappist-1e is an exoplanet 40 light-years away orbiting Trappist-1, an extremely cool ultra-dwarf star with a temperature less than 2700 K.
