TRAPPIST-1d has an equilibrium temperature of 282.1 K (9.0 °C; 48.1 °F), assuming an albedo of 0. [8] For an Earth-like albedo of 0.3, the planet's equilibrium temperature is around 258 K (−15 °C; 5 °F), …

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

TRAPPIST-1d has an equilibrium temperature of 282.1 K (9.0 °C; 48.1 °F), assuming an albedo of 0. For an Earth-like albedo of 0.3, the planet's equilibrium temperature is around 258 K (−15 °C; 5 °F), very …

Mar 3, 2024 · Surface Temperature of TRAPPIST-1d The equilibrium temperature of TRAPPIST-1d is approximately 286.2 286.2 K, which is equivalent to 13.1 ° 13.1 °C or 55.5 ° 55.5 °F.

Aug 11, 2025 · In particular, the 0.8 Earth-radii planet TRAPPIST-1 d lies at the edge of the habitable zone (equilibrium temperature ~262 K). Here we present the first 0.6-5.2 micron NIRSpec/PRISM …

Jun 25, 2025 · TRAPPIST-1 d is a terrestrial exoplanet that orbits a M-type star. Its mass is 0.388 Earths, it takes 4 days to complete one orbit of its star, and is 0.02227 AU from its star.

Here, we showed that the TRAPPIST-1 system can have different climates and that equilibrium temperatures depend on the global albedo, that is, on the mean physical conditions of the planetary …

In 2017, further analysis of the original observations identified five more terrestrial planets. The seven planets take between 1.5 and 19 days to orbit the star in circular orbits. They are all likely tidally …
