It’s one of the closest exoplanets we’ve found to Earth—both literally and figuratively.

The long-rumored, newly unveiled Proxima b zips around its star, the red dwarf Proxima Centauri, in just 11.2 days. The small star casts a dim reddish light, which means that despite its close orbit, Proxima b sits right in the habitable zone where liquid water could exist. Its just 1.3 times bigger than Earth and is relatively close—just 4.24 light years away.

Astronomer Guillem Anglada-Escudé, a lecturer at Queen Mary University in London, and his team pored over data collected between 2000 and 2014 by two European Southern Observatory telescopes, finding faint evidence of Proxima b. They then confirmed their findings earlier this year through a series of observations specifically intended to detect the exoplanet.
