Kepler-202 and Its Two Super-Earths

Kepler-202 is a star 930 light-years from Earth with two known planets, both discovered by transit in 2014. Its age is 3.24 billion years, and its mass is 0.78 solar masses, its radius is 0.73 solar radii, and its temperature is 4790 K. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.

Both planets are classified as Super-Earths, a size class that reaches 2.5 times Earth's radius. Kepler-202 b has an orbital period of 4.07 days and a radius of 1.63 Earth radii. Kepler-202 c has an orbital period of 16.3 days and a radius of 1.85 Earth radii. Each planet's reported radius estimate is larger than Earth's; among the listed planets, Kepler-202 b has the shortest year and the smallest radius, while Kepler-202 c has the longest year and the largest radius.
