The Kepler-67 Exoplanetary System
Kepler-67 is a star with 0.86 times the mass of the Sun, and 0.78 times its radius. It is located 3610.55 light years away from the solar system and is estimated to be 1 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
Kepler-67 is known to have 1 exoplanets in orbit around it.
Kepler-67 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2013-07. Its semi-major axis is 0.12 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 15.73 Earth days to complete an orbit around its host star, Kepler-67.
The mass of Kepler-67 b is 12.77 times the mass of Earth. The radius of Kepler-67 b is 2.94 that of Earth. At more than 10 Earth masses, Kepler-67 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.
