Kepler-283 and Its Two Super-Earths

Kepler-283 is a star located 1530 light-years away. Its reported mass estimate is 0.63 solar masses and its reported radius estimate is 0.6 solar radii, both smaller than the Sun's. The star's reported temperature is 4250 K, cooler than the Sun's, and its age is 3.09 billion years. Two planets are known to orbit this host: Kepler-283 b and Kepler-283 c. Both 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.

Both planets are classified as Super-Earths, a size class that reaches 2.5 times Earth's radius. Kepler-283 b has a reported radius estimate of 2.13 Earth radii and an orbital period of 11 days, the shortest year among the listed planets. Kepler-283 c has a reported radius estimate of 1.82 Earth radii and an orbital period of 92.7 days, the longest year among the listed planets. Both radii are larger than Earth's, and Kepler-283 c has the smallest radius among the listed planets while Kepler-283 b has the largest.
