K2-248 and Its Neptune-Like Planet
K2-248 is a star 1330 light-years away with one known planet. The host star has a mass of 0.88 solar masses and a radius of 0.92 solar radii, both smaller than the Sun's corresponding values. Its temperature is 5530 K, cooler than the Sun's.
The system's only cataloged planet is K2-248 b, a Neptune-like world discovered by transit in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-248 b has a radius of 2.57 Earth radii, larger than Earth's, and completes an orbit every 7.17 days.
