K2-272 b: A Neptune-Like World Orbiting a Cooler Star
K2-272 is a star located 1380 light-years away, with a mass 0.93 solar masses and a radius of 0.818 solar radii. Its reported temperature is 5360 K. The star hosts one known planet.
That planet is K2-272 b, a Neptune-like world discovered by the transit method in 2018. During a transit, a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods. K2-272 b completes one orbit every 14.5 days and has a radius of 3.13 Earth radii. Its radius is larger than Earth's. The host star's mass and radius are both smaller than the Sun's, and its temperature is cooler than the Sun's.
