K2-127 b: A Distant Jupiter-Like World
K2-127 is a star 2320 light-years away with one known planet. The star has a reported mass estimate of 0.72 solar masses, a reported radius estimate of 0.66 solar radii, and a temperature of 4580 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler than the Sun's.
The planet K2-127 b is a Jupiter-like world discovered by transit in 2017. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-127 b orbits its star every 3.59 days and has a radius of 8.37 Earth radii, larger than Earth's. Jupiter-like planets exceed 4 times Earth's radius, so this measurement places the planet well within that size class.
