K2-130 b: An Earth-Like World Around a Cool Dwarf Star
K2-130 is a star 385 light-years away with one known planet, K2-130 b. The star's reported mass estimate is 0.675 solar masses and its reported radius estimate is 0.644 solar radii, both smaller than the Sun's. Its reported temperature is 4530 K, cooler than the Sun's.
K2-130 b was discovered in 2017 by the transit method, which detects the small dip in a star's observed brightness when a planet passes in front of it from our viewpoint. Repeated dips help establish the planet's orbital period. K2-130 b completes one orbit in 2.49 days, and its radius is 1.25 Earth radii. Its reported radius estimate is larger than Earth's, placing it within the Earth-like size class, which covers planets up to 1.5 times Earth's radius.
