Kepler-306 and Its Four Super-Earths

Kepler-306 is a star located 2530 light-years away. It hosts four planets. The star is 2.63 billion years old, has a mass of 0.81 solar masses, a radius of 0.74 solar radii, and a temperature of 5010 K. Its mass, radius, and temperature are all smaller or cooler than the Sun's.

All four planets were discovered by transit in 2014, and each is classified as a Super-Earth. Kepler-306 b has an orbital period of 4.65 days and a radius of 1.52 Earth radii. Kepler-306 c has an orbital period of 7.24 days and a radius of 2.35 Earth radii. Kepler-306 d has an orbital period of 17.3 days and a radius of 2.47 Earth radii. Kepler-306 e has an orbital period of 44.8 days and a radius of 2.27 Earth radii. Each planet's radius is larger than Earth's.

Among the listed planets, Kepler-306 b has the shortest year and the smallest radius, while Kepler-306 e has the longest year and the second-smallest radius. Kepler-306 c has the second-shortest year and the second-largest radius, and Kepler-306 d has the second-longest year and the largest radius.
