Possible 3rd planet spotted around Proxima Centauri, the sun’s nearest neighbor star

The sun’s nearest neighbor may actually host three planets, a new study reports.

Astronomers have found evidence of a third planet circling Proxima Centauri, a red dwarf star that lies a mere 4.2 light-years from our solar system. The candidate world, known as Proxima d, is estimated to be just 25% as massive as Earth, making it one of the lightest known exoplanets if it ends up being confirmed.
