Kepler-452 and Its Super-Earth
Kepler-452 is a G2 star located 1800 light-years away. It has one known planet, Kepler-452 b. The star is 6 billion years old, holds 1.04 solar masses, spans 1.11 solar radii, and has a temperature of 5760 K. Its radius estimate is larger than the Sun's.
Kepler-452 b is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Its radius estimate is 1.63 Earth radii, larger than Earth's. The planet completes an orbit every 385 days. It was discovered in 2015 by the transit method, in which a planet passing in front of its star from our viewpoint causes a small dip in observed brightness.
