In addition to being roughly Earth-sized and lying within its star's habitable zone, Kepler-452b is like Earth in some other ways. It orbits at a distance about 5% further from its star than the Earth is from the Sun. As a result, its year is almost the same length as ours, at roughly 385 days.It has an equilibrium temperature of 265 K (−8 °C; 17 °F), a little warmer than Earth.385 daysKepler-452b / Orbital period
For instance, Kepler-452b takes 385 Earth days to complete its orbit around its star, which is only a bit longer than one Earth year.
Does Kepler-452b have oxygen : It may also have a thick atmosphere with clouds covering most of its surface. We don't know what the atmosphere of the planet is made of, so we don't know whether you could breathe the air there. It's very unlikely to be the same mix of oxygen and nitrogen as the Earth's atmosphere though.
Can Kepler-452b sustain life
Astronomers say that the planet is in the “Goldilocks zone”, meaning that the distance of the planet from its star is just right, making it not too hot and not too cold for life to exist. The same is true of the Earth in our own solar system.
Is Kepler-452b too hot : Thus, the global-mean SAT can be above 380 K for 1 bar CO2. It suggests that Kepler 452b's global-mean SAT could be too hot to be habitable if there is no silicate weathering to limit CO2 concentrations in the atmosphere. Figure 3.
In July 2015, NASA announced the discovery of Kepler-452b, an exoplanet a little over 1½ times wider than Earth orbiting a G2-type star similar to our own Sun. Moreover, Kepler-452b's orbit is located in the “Goldilocks Zone” of its star system where the temperature is just right for liquid water to exist.
