The Kepler-263 Exoplanetary System
Kepler-263 is a star with 0.685 times the mass of the Sun, and 0.79 times its radius. It is located 2514.96 light years away from the solar system.
Kepler-263 is known to have 2 exoplanets in orbit around it.
Kepler-263 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2014-03. Its semi-major axis is 0.12 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 16.57 Earth days to complete an orbit around its host star, Kepler-263.
The mass of Kepler-263 b is 10.14 times the mass of Earth. The radius of Kepler-263 b is 2.67 that of Earth. At more than 10 Earth masses, Kepler-263 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.
