The K2-230 Exoplanetary System
K2-230 is a star with 1.11 times the mass of the Sun, and 1.39 times its radius. It is located 1790.27 light years away from the solar system.
K2-230 is known to have 1 exoplanets in orbit around it.
K2-230 b was discovered by the K2 observatory using the transit method. Its discovery was announced in 2018-02. Its semi-major axis is 0.04 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 2.86 Earth days to complete an orbit around its host star, K2-230.
The mass of K2-230 b is 4.85 times the mass of Earth. The radius of K2-230 b is 1.96 that of Earth. At 4.85 Earth masses, K2-230 b is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. No Super Earths are known to exist in our solar system, but if it exists, the so-called Planet Nine could very well be a super Earth, as it is hypothesized to have a mass between five and ten Earth masses.
