Kepler-280: A Distant Star With Two Small Worlds

Kepler-280 is a star 2550 light-years away with two known planets. The host star is 4.27 billion years old, has 0.96 solar masses, 0.93 solar radii, and a temperature of 5660 K. Its reported temperature is cooler than the Sun's.

Both planets were discovered by transit in 2014, the method in which a planet crosses in front of its star and causes a small dip in brightness. Kepler-280 b is classified as Earth-like, with a radius of 1.45 Earth radii and an orbital period of 2.14 days. Kepler-280 c is classified as a Super-Earth, with a radius of 2.01 Earth radii and an orbital period of 4.81 days. Among the listed planets, Kepler-280 b has the shortest year and the smallest radius, while Kepler-280 c has the longest year and the largest radius. Kepler-280 c's reported radius estimate is larger than Earth's.
