Kepler-300 and Its Two Super-Earths
Kepler-300 is a star located 3580 light-years away, and two planets have been found orbiting it. The star is 3.63 billion years old, with a mass of 1.07 solar masses and a radius of 1.1 solar radii. Its reported temperature of 5970 K is hotter than the Sun's, and its reported mass estimate is larger than the Sun's.
Both planets were discovered by transit in 2014, the method in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Kepler-300 b is a Super-Earth with a radius of 1.67 Earth radii and an orbital period of 10.4 days. Kepler-300 c is also a Super-Earth, with a radius of 2.25 Earth radii and an orbital period of 40.7 days.
Among the listed planets, Kepler-300 b has the shortest year and the smallest radius by reported estimates, while Kepler-300 c has the longest year and the largest radius. Kepler-300 c's reported radius estimate is larger than Earth's.
