Proxima Centauri b probably did not form at its current distance to Proxima Centauri, as the amount of material in the protoplanetary disk would be insufficient.
Proxima Centauri, being a red dwarf, has a luminosity only 0.15% of that emitted by the Sun, and its effective temperature is 3050 K. Therefore, a planet located at 0.05 au from Proxima Centauri has an equilibrium tem...
Planet semi-major axis, eccentricity, equilibrium temperature entered as ranges across several different models (Beichman & Sanghi et al. 2025) Planet radius, semi-major axis, and orbital inclination estimated from ra...
The equilibrium temperature of Proxima Centauri b is estimated to be around 234 K (-39 °C or -38 °F). However, this is just an estimate, and the actual temperature could vary significantly depending on the planet’s at...
After presenting the details about the physical parameteriza-tions used to model Proxima b, Sects. 3 to 5 contain our ma-jor findings about the climate regimes achievable on Proxima b.
Due to its large distance from Proxima Centauri, the exoplanet is unlikely to be habitable, with a low equilibrium temperature of around 39 K. The planet was first reported by Italian astrophysicist Mario Damasso and ...
In short, the equilibrium temperature of Proxima Centauri b is predicted to be just a bit lower than Earth's -- very roughly 243 K = -30 Celsius. That's cold, sure, but no worse than the province of Alberta, Canada, i...
Due to Proxima Centauri C being too cold and Proxima Centauri D being too hot, only Proxima Centauri B remains as a possible colonization target for our future missions outside of the solar system.
Tutorial models of the climate and habitability of Proxima Centauri b: a thin atmosphere is sufficient to distribute heat given low stellar flux 2016 GOLDBLATT C.
In this work, we use the PlanetSimulator (PlaSim), an intermediate complexity 3D GCM, a flexible and fast model, suited to handle all the orbital and physical parameters of a planet and to study the dynamics of its at...
