K2-318 and Its Super-Earth

K2-318 is a star 482 light-years away with one known planet. The star's reported mass estimate is 0.552 solar masses, its radius is 0.557 solar radii, and its temperature is 3710 K. These values are smaller and cooler than the Sun's.

The planet K2-318 b is classified as a Super-Earth, meaning its radius reaches up to 2.5 times Earth's. Its radius is 1.66 Earth radii, larger than Earth's. It was discovered by transit in 2020, when it passed in front of its star from our viewpoint and caused a small dip in observed brightness. Its orbital period is 7.01 days.
