The planet was announced in the media as being located within the star's "habitable zone", a region where liquid water could exist on the surface of the planet. It was described as being one of the most Earth-like planets, in terms of size and temperature yet found and, according to the scientists, a "prime candidate to host alien life". Due to uncertainties in the stellar parameters, the error bars on the value of the incident flux on this planet are quite large, at 1.91+0.43
−0.56 times the level of Earth. Using the nominal parameters, the planet is too close to the star to be habitable, though the uncertainties allow for the possibility that it may actually lie in the innermost region of the habitable zone. A more recent analysis has shown that the planet is likely more analogous to Venus, which is known to be one of the most inhospitable places to life as we know it in the Solar System, and thus unlikely to be habitable to such organisms.
The host star, Kepler-69 (KIC 8692861, 2MASS J19330262+4452080), is a G-type main-sequence star somewhat cooler than the Sun. On April 18, 2013, it was announced that two planets orbit Kepler-69: an inner planet, Kepler-69b, and an outer planet, Kepler-69c. Kepler-69c is about 70 million miles from its host star (compared to 93 million miles between Earth and the Sun) and takes 242 days to orbit its star (compared to the 365 days of Earth).
