Kepler-407 and Its Two Known Worlds

Kepler-407 is a G-type star located 1100 light-years away. Its mass is 0.99 solar masses, its radius is 1.04 solar radii, and its temperature is 5490 K. Its reported temperature is cooler than the Sun's. Two planets are known to orbit this host.

Kepler-407 b was discovered by the transit method in 2014. Its radius is 1.19 Earth radii and its mass is 1.93 Earth masses, both larger than Earth's. With a mean density of 6.31 g/cm³, 1.15 times Earth's, it is classified as Earth-like. Its orbital period is 0.669 days, the shortest year among the listed planets; its mass is also the smallest among them.

Kepler-407 c, discovered in 2014 by the radial velocity method, has a mass of 4000 Earth masses, roughly 12.6 times Jupiter's mass and larger than Earth's. Among the listed planets it has both the largest reported mass and the longest year, with an orbital period of 3000 days.
