4546C

4546C is a planet located in the Kepler-452 system, approximately 1,400 light-years away from Earth. It orbits a G-type star, similar to our Sun, within the star's habitable zone. This means that conditions on 4546C could potentially allow for liquid water to exist on its surface, a key ingredient for life as we know it.

The planet is estimated to be about 60% larger in diameter than Earth and has a slightly longer orbital period, taking approximately 385 Earth days to complete one revolution around its star. Its mass and composition are not yet precisely determined, but its size suggests it is likely a rocky planet. Scientists believe that 4546C may have a thicker atmosphere than Earth, which could contribute to a warmer surface temperature.

The discovery of 4546C was made by NASA's Kepler space telescope, which is dedicated to searching for exoplanets. Its location in the habitable zone of a Sun-like star has made it a significant find in the ongoing quest to discover Earth-like worlds beyond our solar system. Further observations and research are needed to learn more about its atmosphere, surface conditions, and the possibility of life.
