K2-238 b: A Jupiter-Like World Around a Sun-Like Star
K2-238 is a G-type main-sequence star located 1750 light-years away. It is larger than the Sun in both mass and radius, at 1.19 solar masses and 1.59 solar radii, and cooler, with a temperature of 5630 K. Its age is 5.63 billion years. One planet orbits this host.
That planet is K2-238 b, a Jupiter-like world discovered by the transit method in 2018. Its radius is 14.6 Earth radii, which is larger than Earth's, and its mass is 273 Earth masses, also larger than Earth's. It completes one orbit every 3.2 days. Its mean density is 0.487 g/cm³, 0.0883 times Earth's.
