K2-200 and Its Earth-Like Planet

K2-200 is a single star located 601 light-years away. Its mass is 0.834 solar masses and its radius is 0.808 solar radii, both smaller than the Sun's. The star's temperature is 5020 K, cooler than the Sun's. One known planet orbits this host.

That planet, K2-200 b, was discovered in 2018 by the transit method, which detects the small dip in a star's brightness when a planet crosses in front of it from our viewpoint. K2-200 b has an orbital period of 2.85 days. Its radius is 1.36 Earth radii, larger than Earth's. This places it within the Earth-like size class, which covers planets up to 1.5 times Earth's radius.
