GJ 849 is a star with 0.65 times the mass of the Sun, and 0.53 times its radius. It is located 28.70 light years away from the solar system and is estimated to be 3 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
GJ 849 is known to have 1 exoplanets in orbit around it.
GJ 849 b was discovered by the W. M. Keck Observatory observatory, in 2006-12, using the radial velocity method. Its semi-major axis is 2.35 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of GJ 849 b is 318.000 times the mass of Earth. The radius of GJ 849 b is 13.800 that of Earth. At more than 50 Earth masses, GJ 849 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.
