K2-276 b: A Neptune-Like World in a Distant System
K2-276 is a star located 1590 light-years away. It has a mass of 0.82 solar masses and a radius of 0.85 solar radii, making it smaller than the Sun in both respects. Its temperature of 5140 K is cooler than the Sun's. One planet orbits this star.
That planet, K2-276 b, is a Neptune-like world discovered in 2018 by the transit method, which detects the slight dimming of a star's brightness as a planet crosses in front of it. K2-276 b completes an orbit every 18.7 days. Its radius is 3.77 Earth radii, larger than Earth's.
