The artist's concept depicts Kepler-69c, a super-Earth-size planet in the habitable zone of a star like our Sun, located about 2,700 light-years from Earth in the constellation Cygnus.
Kepler-69c, is 70 percent larger than the size of Earth, and is the smallest yet found to orbit in the habitable zone of a Sun-like star. Astronomers are uncertain about the composition of Kepler-69c, but its orbit of 242 days around a sun-like star resembles that of our neighboring planet Venus.
