Kepler-1398 and Its Two Planets

Kepler-1398 is a star located 2780 light-years away. It has 1.13 solar masses, 1.18 solar radii, and a temperature of 6130 K, and its age is 3.09 billion years. Its reported mass, radius, and temperature are all larger or hotter than the Sun's. Two planets are known to orbit this host.

Kepler-1398 b is a Sub-Earth discovered by transit in 2016. Its radius is 0.9 Earth radii, and its orbital period is 2.79 days. Kepler-1398 c is an Earth-like planet, also discovered by transit in 2016, with a radius of 1.03 Earth radii and an orbital period of 4.14 days.

Both planets complete their orbits quickly. Among the listed planets, Kepler-1398 b has the shortest year, at 2.79 days, and the smallest radius, at 0.9 Earth radii. Kepler-1398 c has the longest year, at 4.14 days, and the largest radius, at 1.03 Earth radii.
