Kepler-69

Kepler-69 (also known as KOI-172, 2MASS J19330262+4452080 and KIC 8692861) is a G-type main sequence star that is similar to the Sun. It is located about 2,430 light years away from the Earth in the constellation Cygnus. It has a radius of 0.93 times smaller than the Sun. On April 18, 2013 It was announced that two exoplanets were found orbiting this star,^[1]^[2] but further studies have shown that the terrestrial planet Kepler-69c is not in the habitable zone and is more like Venus than Earth, making it a lifeless planet.
