Kepler-888 and Its Super-Earth
Kepler-888 is a star located 1370 light-years from Earth. It hosts one known planet. The star is 1.48 billion years old and has a mass of 0.97 solar masses and a radius of 0.9 solar radii, making its radius smaller than the Sun's. Its temperature of 5880 K is hotter than the Sun's.
The planet, Kepler-888 b, was discovered in 2016 by the transit method, in which a planet passing in front of its star from our viewpoint causes a small dip in observed brightness. It is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Its radius of 1.76 Earth radii is larger than Earth's, and it completes an orbit every 70.7 days.
