K2-336 b: An Earth-Like World in a Distant System
K2-336 is a star located 780 light-years away, and it hosts one known planet. The star has a mass of 0.91 solar masses, a radius of 0.798 solar radii, and a temperature of 5300 K. Its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet K2-336 b was discovered by transit in 2021, when it passed in front of its star from our viewpoint and caused a small dip in observed brightness. It completes an orbit every 21.2 days. With a radius of 1.22 Earth radii, it is classified as Earth-like, since an Earth-like planet stays within 1.5 times Earth's radius. Its reported radius estimate is larger than Earth's.
