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 …

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.

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

0.0000 wly-discovered TRAPPIST-1 planets, taken from Gi lon et al. (2016). The orbit of TRAPPIST-1d is not yet constrained. Masses, scale heights and gravities are estimates based …

Oct 15, 2024 · TRAPPIST-1d has an equilibrium temperature of 286.2 K. Less than 5 percent of its mass is composed of volatile materials, which could indicate an atmosphere, ice layers, or …

Oct 4, 2024 · With these assumptions, all we need to know to compute the equilibrium temperature are two items: the host star's luminosity L, and the orbital radius of the exoplanet a.
