Kepler-273 and Its Two Super-Earths

Kepler-273 is a star 2330 light-years away with two planets. The star is 4.68 billion years old, has 0.94 solar masses and 0.92 solar radii, and a temperature of 5580 K. Its reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.

Both planets 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. Kepler-273 b is a Super-Earth with a radius of 1.5 Earth radii and an orbital period of 2.94 days, the shortest year among the listed planets. Kepler-273 c is also a Super-Earth, with a radius of 1.98 Earth radii and an orbital period of 8.01 days, the longest year among the listed planets. Among the listed planets, Kepler-273 b has the smallest radius, while Kepler-273 c has the largest.
