K2-147 b: A Close-Orbiting Earth-Like Planet
K2-147 is a star located 295 light-years away, and it hosts one known planet. The star has a reported mass of 0.583 solar masses and a radius of 0.554 solar radii, both smaller than the Sun's corresponding values. Its temperature is 3670 K, cooler than the Sun.
The planet K2-147 b was discovered by the transit method in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-147 b completes an orbit in 0.962 days. Its radius is 1.47 Earth radii, which is larger than Earth's and places it within the Earth-like size class, where a planet stays within 1.5 times Earth's radius.
