K2-10 and Its Neptune-Like Planet
K2-10 is an F9 star located 888 light-years from Earth. Its mass is 0.973 solar masses and its radius is 0.969 solar radii, while its temperature of 5530 K is cooler than the Sun's. One planet orbits this host.
That planet is K2-10 b, a Neptune-like world discovered by transit in 2015. It completes an orbit every 19.3 days. Its radius is 3.77 Earth radii, larger than Earth's, and its mass estimate is 25.2 Earth masses, also larger than Earth's. Its mean density is 2.59 g/cm³, 0.469 times Earth's.
