Kepler-165 and Its Two Super-Earths

Kepler-165 is a star located 1830 light-years away, and two planets orbit it. The star is 5.01 billion years old and has a mass of 0.8 solar masses, a radius of 0.76 solar radii, and a temperature of 5110 K. Its reported mass and radius estimates are smaller than the Sun's, and its temperature is cooler than the Sun's. Both planets were discovered in 2014 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness.

Kepler-165 b and Kepler-165 c are both Super-Earths, a size class that reaches 2.5 times Earth's radius. Kepler-165 b has an orbital period of 8.18 days and a radius of 2.32 Earth radii, making it the largest of the two planets and the one with the shortest orbital period among the listed planets. Kepler-165 c has an orbital period of 15.3 days and a radius of 2.23 Earth radii, giving it the smallest radius and the longest orbital period among the listed planets.
