K2-383 b: A Super-Earth
K2-383 is a star located 665 light-years away. It has a mass of 1.06 solar masses, a radius of 0.804 solar radii, and a temperature of 5130 K. Its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
That planet is K2-383 b, classified as a Super-Earth. A Super-Earth is a size class reaching up to 2.5 times Earth's radius. Discovered by transit in 2022, K2-383 b has an orbital period of 1.87 days. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-383 b's reported radius estimate is larger than Earth's, at 1.56 Earth radii.
