The Kepler-276 Exoplanetary System
Kepler-276 is a star with 1.0220000000000002 times the mass of the Sun, and 1.05 times its radius. It is located 3854.28 light years away from the solar system.
Kepler-276 is known to have 3 exoplanets in orbit around it.
Kepler-276 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2014-03. Its semi-major axis is 0.12 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 14.13 Earth days to complete an orbit around its host star, Kepler-276.
The mass of Kepler-276 b is 12.08 times the mass of Earth. The radius of Kepler-276 b is 2.87 that of Earth. At more than 10 Earth masses, Kepler-276 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.
