The K2-49 Exoplanetary System
K2-49 is a star with 0.51 times the mass of the Sun, and 0.45 times its radius. It is located 1510.30 light years away from the solar system.
K2-49 is known to have 1 exoplanets in orbit around it.
K2-49 b was discovered by the K2 observatory using the transit method. Its semi-major axis is 0.03 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 2.77 Earth days to complete an orbit around its host star, K2-49.
The mass of K2-49 b is 4.65 times the mass of Earth. The radius of K2-49 b is 1.93 that of Earth. At 4.65 Earth masses, K2-49 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.
