K2-241: A Cool, Compact Star With One Known Planet
K2-241 is a star located 487 light-years away. It has a mass of 0.71 solar masses and a radius of 0.75 solar radii, both smaller than the Sun's. Its temperature of 5260 K is cooler than the Sun's. One planet is known to orbit this star.
That planet, K2-241 b, is a Neptune-like world 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. K2-241 b completes an orbit every 26.8 days and has a radius of 2.55 Earth radii, making it larger than Earth.
