K2-255 and Its Neptune-Like Planet
K2-255 is a star 625 light-years away with one known planet, K2-255 b. The host star has a mass of 0.67 solar masses and a radius of 0.786 solar radii, and its temperature is 4300 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
K2-255 b is a Neptune-like planet 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 orbits every 1.96 days and has a radius of 2.9 Earth radii, larger than Earth's.
