Kepler-336 and Its Three Worlds

Kepler-336 is a star located 2510 light-years away. It is 4.9 billion years old and has a mass of 1.09 solar masses, a radius of 1.21 solar radii, and a temperature of 5910 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. Three planets are known to orbit this host.

Kepler-336 b, Kepler-336 c, and Kepler-336 d were all discovered in 2014 using the transit method, which detects the small dip in a star's brightness when a planet passes in front of it from our viewpoint.

Kepler-336 b is classified as Earth-like, a size class for planets whose radius stays within 1.5 times Earth's. It has an orbital period of 2.02 days and a radius of 1.02 Earth radii. Among the listed planets, it has the shortest year and the smallest radius.

Kepler-336 c is a Super-Earth, a size class reaching up to 2.5 times Earth's radius. Its radius is 2.1 Earth radii, larger than Earth's, and its orbital period is 9.6 days. Among the listed planets, it has the second-shortest year and the second-smallest radius.

Kepler-336 d is also a Super-Earth. It has an orbital period of 20.7 days and a radius of 2.37 Earth radii, larger than Earth's. Among the listed planets, it has the longest year and the largest radius.
