New planet outside solar system discovered
The Gliese 22 star system is made up of three low-mass stars. Two of them form a binary system, in which both circle around a common centre of mass, while the third star - the most distant of the trio - circles around the other two.

The existence of the enormous planet, which is calculated to have 16 times the mass of Jupiter - our solar system's largest planet, was detected around the third lone star.
