The Kepler-58 Exoplanetary System
Kepler-58 is a star with 1.1839999999999997 times the mass of the Sun, and 1.13 times its radius. It is located 3249.56 light years away from the solar system.
Kepler-58 is known to have 3 exoplanets in orbit around it.
Kepler-58 d was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2014-03. Its semi-major axis is 0.24 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 40.10 Earth days to complete an orbit around its host star, Kepler-58.
The mass of Kepler-58 d is 12.77 times the mass of Earth. The radius of Kepler-58 d is 2.94 that of Earth. At more than 10 Earth masses, Kepler-58 d 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.
