Earth Similarity Index: 75%

Nearly 600 light years away lies a little planet called Kepler-22b, which might very well be considered Earth’s long forgotten sister. Kepler has a very similar orbit and its years lasts 290 days. The surface temperature is believed to also be similar to our own, but there is little info whether Kepler’s atmosphere could facilitate life on the planet, or dismiss it all together.
