HD 9446 is a star with 1 times the mass of the Sun, and 1 times its radius. It is located 164.22 light years away from the solar system.
HD 9446 is known to have 2 exoplanets in orbit around it.
HD 9446 b was discovered by the Haute-Provence Observatory observatory, in 2010-04, using the radial velocity method. Its semi-major axis is 0.19 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HD 9446 b is 222.600 times the mass of Earth. The radius of HD 9446 b is 14.000 that of Earth. At more than 50 Earth masses, HD 9446 b is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn in our solar system.
HD 9446 c was discovered by the Haute-Provence Observatory observatory, in 2010-04, using the radial velocity method. Its semi-major axis is 0.65 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HD 9446 c is 578.760 times the mass of Earth. The radius of HD 9446 c is 13.400 that of Earth. At more than 50 Earth masses, HD 9446 c is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn in our solar system.
