What is Proxima Centauri b?
[[File:Proxima Centauri b (29196109016).png|alt=An artist's view of Proxima Centauri b|thumb|An artist's view of the Proxima Centauri b]] '''Proxima Centauri b''' is a planet orbiting [[Proxima Centauri]], the Sun's closest stellar neighbor. The planet is in Proxima Centauri's [[habitable zone]] and is a terrestrial planet a bit bigger than [[Earth]], so it could be an Earth-like planet with lakes, rivers an ocean and complex [[extraterrestrial life]]. The planet is 7.5 million kilometres on average from Proxima Centauri and is likely to either be tidally locked or have an [[orbital resonance]] similar to that of [[Mercury (planet)|Mercury]]. The biggest potential strike against Proximal b's habitability is that its star is prone to flares. [[Category:Exoplanets]] [[Category:Terrestrial planets]]
