K2-339 and Its Super-Earth
K2-339 is a star 1180 light-years away with a mass of 0.75 solar masses, a radius of 0.719 solar radii, and a temperature of 4680 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler. One planet is known to orbit this star.
That planet, K2-339 b, is a Super-Earth discovered by transit in 2021. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-339 b orbits every 19.5 days, and its radius of 1.92 Earth radii is larger than Earth's.
