Wolf 503 and Its Super-Earth
Wolf 503 is a K3.5 V star located 145 light-years away. This K-type main-sequence dwarf has 0.688 solar masses, 0.69 solar radii and an age of 11 billion years. Its temperature is 4720 K, cooler than the Sun, and both its mass and radius are smaller than the Sun's. One planet orbits this host.
Wolf 503 b is a Super-Earth discovered by transit in 2018. It orbits every 6 days, with a radius of 2.04 Earth radii and a mass of 6.26 Earth masses, both larger than Earth's. Its mean density is 4.05 g/cm³, 0.734 times Earth's.
