K2-275 is known to have 2 exoplanets in orbit around it.
K2-275 b was discovered by the K2 observatory, in 2018-12, using the transit method. Its semi-major axis is 0.04 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of K2-275 b is 5.660 times the mass of Earth. The radius of K2-275 b is 2.240 that of Earth. At more than 10 Earth masses, K2-275 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.
K2-275 c was discovered by the K2 observatory, in 2018-12, using the transit method. Its semi-major axis is 0.07 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of K2-275 c is 6.074 times the mass of Earth. The radius of K2-275 c is 2.340 that of Earth. At more than 10 Earth masses, K2-275 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.
