The Kepler-27 Exoplanetary System
Kepler-27 is a star with 0.65 times the mass of the Sun, and 0.59 times its radius. It is located 3506.50 light years away from the solar system.
Kepler-27 is known to have 2 exoplanets in orbit around it.
Kepler-27 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2012-04. Its semi-major axis is 0.12 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 15.33 Earth days to complete an orbit around its host star, Kepler-27.
The mass of Kepler-27 b is 2895.25 times the mass of Earth. The radius of Kepler-27 b is 4 that of Earth. At more than 50 Earth masses, Kepler-27 b is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn in our solar system.
