Kepler – 186 f – It was the first exoplanet of the size of the Earth found in a habitable zone and had an orbit of one hundred and thirty Earth days and is nearly 10% larger than the Earth. It seems like Kepler – 186 f would be a good candidate to have liquid water, and probably life. However, it is 490 light-years away from the Earth, in the Cygnus constellation.
Kepler-62 f – This planet circles around Kepler-62, nearly 1,200 light-years away from the Earth. As per recent research, astronomers believe that this exoplanet may be water-world, similar to the Earth. It is almost 1.4 times bigger than the Earth. Kepler-1229 b – It orbits a K-type star. However, this super-Earth takes almost 86.8 days to complete an orbit around an orange dwarf, Kepler- 1229 that is 770 light-years away from the Earth.
