[3] Due to its large mass and its distance from Proxima Centauri, the exoplanet is uninhabitable and too cold for liquid water to exist on the surface, with an equilibrium temperature of approximately 39 K (−234.2 °C; −389.5 °F).

Damasso's team had noticed minor movements of Proxima Centauri in the radial velocity data from the ESO's HARPS instrument, analyzed earlier by Ukrainian astrophysicist Yakiv Pavlenko and his colleages at the Instituto de Astrofísica de Canarias,[7][8][9] indicating a possible second planet orbiting Proxima Centauri.

[1]Red dwarfs has wide developed convection zones, where magnetic fields are forming.

[12] However, a 2022 study questioned the planetary nature of the observed radial velocity signal corresponding to Proxima c, attributing it to systematic effects.

[4] If this is the case, it is unclear why astrometric observations detected what appeared to be a similar planetary signature.
