HAT-P-26 is a star with 1.12 times the mass of the Sun, and 0.87 times its radius. It is located 462.61 light years away from the solar system and is estimated to be 9 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
HAT-P-26 is known to have 1 exoplanets in orbit around it.
HAT-P-26 b was discovered by the HATNet observatory, in 2011-02, using the transit method. Its semi-major axis is 0.05 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of HAT-P-26 b is 22.260 times the mass of Earth. The radius of HAT-P-26 b is 7.062 that of Earth. At more than 10 Earth masses, HAT-P-26 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.
