Largest solar system ever known: Planet orbits star 1trn km away:

The giant gas planet – identified only as 2MASS J2126−8140 by scientists – lies 100 light years away from Earth. It’s around 12 to 15 times the mass of Jupiter, the largest planet in our Solar System. 

2MASS J2126−8140’s parent is a red dwarf star called TYC 9486-927-1. It’s so far away that it would take light a whole month to reach the planet.

Dr. Simon Murphy:

We can speculate they formed 10 million to 45 million years ago from a filament of gas that pushed them together in the same direction
