HD 110113 is a star with 1 times the mass of the Sun, and 0.97 times its radius. It is located 346.73 light years away from the solar system and is estimated to be 4 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
HD 110113 is known to have 2 exoplanets in orbit around it.
HD 110113 b was discovered by the Transiting Exoplanet Survey Satellite (TESS) observatory, in 2021-01, 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 HD 110113 b is 4.554 times the mass of Earth. The radius of HD 110113 b is 2.050 that of Earth. With a mass below 5 Earth masses, a density of 2.9, and a semi-major axis of 0.035 astronomical units, HD 110113 b could, potentially, be an ocean world - a planet with no dry land.
HD 110113 c was discovered by the La Silla Observatory observatory, in 2021-01, using the radial velocity method. Its semi-major axis is 0.07 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HD 110113 c is 10.507 times the mass of Earth. The radius of HD 110113 c is 3.230 that of Earth. At more than 10 Earth masses, HD 110113 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.
