K2-213 b: A Super-Earth Orbiting a Star
K2-213 is a star 1270 light-years away. It has 1.07 solar masses, 1.2 solar radii, and a temperature of 5790 K, so its reported mass and radius estimates are both larger than the Sun's. One planet orbits this host.
That planet, K2-213 b, is classified as a Super-Earth and was discovered by transit in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods.
K2-213 b completes an orbit every 8.13 days. Its radius is 1.51 Earth radii, which is larger than Earth's. Earth radii compare radius, not volume. Size classes compare radius with Earth's: a Super-Earth reaches 2.5 times Earth's radius.
