The K2-245 Exoplanetary System
K2-245 is a star with 0.83 times the mass of the Sun, and 1.25 times its radius. It is located 1511.41 light years away from the solar system.
K2-245 is known to have 1 exoplanets in orbit around it.
K2-245 b was discovered by the K2 observatory using the transit method. Its semi-major axis is 0.10 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 11.89 Earth days to complete an orbit around its host star, K2-245.
The mass of K2-245 b is 32.56 times the mass of Earth. The radius of K2-245 b is 4.34 that of Earth. At more than 10 Earth masses, K2-245 b is an ice giant, a planet that is made up mostly of volatiles like water, amonia and methane, and enveloped by a dense hydrogen and helium atmosphere, much like Uranus and Neptune in our solar system.
