Exoplanet Kepler-452b

This artist's concept depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of a star that is similar to our sun. The habitable zone is a region around a star where temperatures are right for water to pool on the surface. Scientists do not know if Kepler-452b can support life or not. What is known about the planet is that it is about 60 percent larger than Earth. Kepler-452b orbits its star every 385 days. The planet's star is about 1,400 light-years away in the constellation Cygnus. It is a G2-type star like our sun, with nearly the same temperature and mass. The star is 6 billion years old, 1.5 billion years older than our sun. If the planet Kepler-452b does in fact have liquid on its surface and has grown warmer due to the older age of its star, it could possibly be experiencing a runaway greenhouse effect, where oceans would begin to evaporate and contribute to increased cloud cover.
