K2-88 b: A Close-In Earth-Like World Around a Small Star
K2-88 is a single star located 361 light-years away, and one planet orbits it. The host star has a mass of 0.437 solar masses and a radius of 0.441 solar radii, with a temperature of 3570 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler than the Sun's.
The planet, K2-88 b, was discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. K2-88 b is classified as Earth-like, meaning its radius stays within 1.5 times Earth's radius, and it has a radius of 1.23 Earth radii. Its orbital period is 4.61 days.
