K2-11 b: A Jupiter-like Planet Orbiting a Sun-like Star
K2-11 is a star located 1070 light-years away. It is a G8 spectral type star with a measured mass of 0.91 solar masses, a radius of 0.847 solar radii, and a temperature of 5310 K. Its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this star.
K2-11 b is a Jupiter-like planet discovered in 2015 by the transit method. It completes an orbit every 39.9 days. Its radius is 7.55 Earth radii, which exceeds four times Earth's radius and places it in the Jupiter-like size class. Size classifications describe radius, not composition. With no reported minimum mass or ordinary mass estimate, no mass information is available for this planet.
