Kepler-452b is classified as a super-Earth and is approximately 1.6 times the radius of Earth. Its mass is estimated to be 5 to 8 times that of Earth, but precise measurements are still uncertain. 

Kepler-452b is located about 1,400 light-years away from Earth in the constellation Cygnus.

Details about the surface conditions of Kepler-452b are still largely unknown. However, since it is in the habitable zone of its star, it may have the potential for liquid water and possibly life. The surface could vary widely, featuring rocky terrain, potential bodies of water, and an atmosphere that may support various environmental conditions. 

The interior composition of Kepler-452b is not directly known, but given its classification as a super-Earth, it is likely to have a rocky composition, possibly with a significant atmosphere. The exact conditions inside the planet, including the potential for a metallic core, remain speculative. 

As of now, there is no confirmed evidence of moons orbiting Kepler-452b. The detection of exomoons is challenging, and while it's possible that Kepler-452b could have moons, no observations have yet confirmed their existence. 

Discovery Method: Transit Method

Year Discovered: 2015

Details: Kepler-452b was discovered by NASA's Kepler Space Telescope. The planet was identified through the detection of a slight dip in brightness of its host star, Kepler-452, as it transited in front of it. Kepler-452b is notable for being in the habitable zone of a G-type star, similar to our Sun.
