K2-63 is a star with 1.4 times the mass of the Sun, and 1.63 times its radius. It is located 1687.97 light years away from the solar system.
K2-63 is known to have 2 exoplanets in orbit around it.
K2-63 b was discovered by the K2 observatory, in 2016-09, using the transit method. Its semi-major axis is 0.16 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of K2-63 b is 10.462 times the mass of Earth. The radius of K2-63 b is 3.220 that of Earth. At more than 10 Earth masses, K2-63 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.
K2-63 c was discovered by the K2 observatory, in 2016-09, using the transit method. Its semi-major axis is 0.19 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of K2-63 c is 14.469 times the mass of Earth. The radius of K2-63 c is 3.900 that of Earth. At more than 10 Earth masses, K2-63 c 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.
