Astronomers discover largest solar system

Astronomers have discovered the largest known solar system, consisting of a large planet that takes nearly a million years to orbit its star.
The gas giant is one trillion kilometres away, making its orbit 140 times wider than Pluto's path around our Sun.
Only a handful of extremely wide pairs of this kind have been found in recent years. Details appear in the Monthly Notices of the Royal Astronomical Society. The planet, known as 2MASS J2126-8140, is between 12 and 15 times the mass of Jupiter.
