K2-249 and Its Neptune-Like Planet

K2-249 is a star 1700 light-years away with one known planet. The host star has a reported mass of 1.32 solar masses and a radius of 1.57 solar radii, both larger than the Sun's. Its temperature is 6500 K, hotter than the Sun.

The planet K2-249 b is 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. The planet's orbital period is 12.4 days, and its radius is 2.79 Earth radii, larger than Earth's.
