K2-212 b: A Neptune-like World in a Distant System
K2-212 is a star located 356 light-years from Earth. It has one known planet. The star's reported mass estimate is 0.67 solar masses, smaller than the Sun's, and its reported radius estimate is 0.65 solar radii, also smaller than the Sun's. Its reported temperature is 4270 K, cooler than the Sun's.
The planet K2-212 b is Neptune-like, a size class that reaches 4 times Earth's radius. It was discovered by transit in 2018, when it passed in front of its star from our viewpoint, causing a small dip in observed brightness. Its orbital period is 9.8 days. Its radius is 2.65 Earth radii, larger than Earth's.
