In case you were thinking of ditching this cold Earth, hold on to your Hyperdrives: Proxima b is way closer to its star, Proxima Centauri, just 5 million miles away, than Earth is to its star, some 93 million miles away. Proxima Centauri is also a Red Dwarf, unlike our Yellow Dwarf, so there's all sorts of differences in mass, light, and other things a guy who writes about Pokémon sex toys can only pretend to understand.
Additionally, while Proxima b is 1.3 times the mass of Earth, its "conditions could be Earthlike, but they could also be hellish like Venus, or cold and dry like Mars." Both also good descriptors for my last relationship! There are no photos of Proxima b, either -- also like my last relationship.
