Kepler 186f: Earth-sized Planet in Habitable Zone

The Kepler mission has discovered an Earth-sized planet that orbits within its host star’s habitable zone: Kepler 186f. The planet is only 11% bigger than Earth.

The planet orbits closer to its star than Earth does to sun, but this places it right inside the habitable zone. According to Wikipedia, it is the equivalent of Mars’ orbit in our solar system.


Unfortunately not much else is known about it, and it is too far away for our current instruments and space telescopes. Still, more data is good. And here at Contact Light we’ve got a whole sky full of terrestrial worlds to justify.
