Kepler-182 and Its Two Planets

Kepler-182 is a star located 5050 light-years away. It is 3.09 billion years old, with a mass of 1.16 solar masses, a radius of 1.23 solar radii, and a temperature of 6120 K. Its reported mass, radius, and temperature estimates are all larger or hotter than the Sun's. Two planets orbit this host.

Both planets were found 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-182 b is Neptune-like, which places it in a size class reaching 4 times Earth's radius. It completes an orbit, or year, in 9.83 days and has a radius of 2.58 Earth radii, larger than Earth's. Among the listed planets, it has the shortest year and the smallest radius by reported estimates. Kepler-182 c is also Neptune-like, with an orbital period of 20.7 days and a radius of 3.43 Earth radii, also larger than Earth's. Among the listed planets, it has the longest year and the largest radius by reported estimates.
