Kepler-1312 is a star with 0.99 times the mass of the Sun, and 0.92 times its radius. It is located 975.55 light years away from the solar system and is estimated to be 2 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
Kepler-1312 is known to have 1 exoplanets in orbit around it.
Kepler-1312 b was discovered by the Kepler observatory, in 2016-05, using the transit method. Its semi-major axis is 0.06 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of Kepler-1312 b is 5.056 times the mass of Earth. The radius of Kepler-1312 b is 2.100 that of Earth. At more than 10 Earth masses, Kepler-1312 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.
