the star hosts one confirmed exoplanet, kepler-452b, discovered in july 2015 by the "kepler" spacecraft. this planet is mostly known for its characteristics similar to earth, most notably its size, orbit and stellar flux. it is the first potentially rocky super-earth planet discovered orbiting within the habitable zone and the abiogenesis zone of a star very similar to the sun. it may even have a surface temperature similar to that of earth (the planet has an equilibrium temperature of approximately (earth's equilibrium temperature is only 10 k cooler than this). however, its star is 6 billion years old (roughly 1.5 billion years older than the sun). due to this, kepler-452b is receiving roughly 10% more stellar radiation than the earth does today. if kepler-452b is a rocky planet, it may be subject to a runaway greenhouse effect. however, because of its mass (estimated to be about 5 ), it may be able to prevent succumbing to the runaway greenhouse for a limited amount of time (at most about 500 million years). nevertheless, the planet is one of the most earth-like planets discovered so far by the "kepler" team.
