The Kepler-279 Exoplanetary System
Kepler-279 is a star with 2.255 times the mass of the Sun, and 1.75 times its radius. It is located 3487.26 light years away from the solar system.
Kepler-279 is known to have 3 exoplanets in orbit around it.
Kepler-279 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2014-03. Its semi-major axis is 0.11 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 12.31 Earth days to complete an orbit around its host star, Kepler-279.
The mass of Kepler-279 b is 21.10 times the mass of Earth. The radius of Kepler-279 b is 3.62 that of Earth. At more than 10 Earth masses, Kepler-279 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.
