The Kepler-104 Exoplanetary System
Kepler-104 is a star with 1.759999999999999 times the mass of the Sun, and 1.35 times its radius. It is located 1322.30 light years away from the solar system.
Kepler-104 is known to have 3 exoplanets in orbit around it.
Kepler-104 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2014-03. Its semi-major axis is 0.09 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 11.43 Earth days to complete an orbit around its host star, Kepler-104.
The mass of Kepler-104 b is 14.59 times the mass of Earth. The radius of Kepler-104 b is 3.1 that of Earth. At more than 10 Earth masses, Kepler-104 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.
