Kepler-140 and Its Two Super-Earths

Kepler-140 is a star located 1900 light-years away, and two planets have been found orbiting it. The host star is 1.95 billion years old, with a mass of 1.15 solar masses and a radius of 1.15 solar radii, making both its reported mass and radius estimates larger than the Sun's. Its temperature of 6110 K is also hotter than the Sun's.

Both planets were discovered by the transit method in 2014, which means each was detected as it passed in front of the star and caused a small dip in observed brightness. Kepler-140 b is a Super-Earth with a radius of 1.61 Earth radii, larger than Earth's, and it completes one orbit every 3.25 days. Kepler-140 c is likewise a Super-Earth, with a radius of 1.8 Earth radii, also larger than Earth's, and an orbital period of 91.4 days. Among the listed planets, Kepler-140 b has the shortest year and the smallest radius by reported estimates, while Kepler-140 c has the longest year and the largest radius.
