The Kepler-340 Exoplanetary System
Kepler-340 is a star with 2.3749999999999996 times the mass of the Sun, and 1.85 times its radius. It is located 2698.65 light years away from the solar system.
Kepler-340 is known to have 2 exoplanets in orbit around it.
Kepler-340 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2014-03. Its semi-major axis is 0.13 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 14.84 Earth days to complete an orbit around its host star, Kepler-340.
The mass of Kepler-340 b is 8.95 times the mass of Earth. The radius of Kepler-340 b is 2.53 that of Earth. At 8.95 Earth masses, Kepler-340 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.
