Blimey they've found another one! "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." That's amaaaaaaaaaaaaaaaaazing, especially those numbers being so nice and round - and BIG! So per ardua ad astra to our boys and girls in white coats. Let's just hope there's some liquid wodda up there. http://www.bbc.co.uk/news/science-environment-35420633 (Good old BBC - in the lead as usual )
One trillion km is like 10% of a light year. The Oort cloud of our Solar System probably stretches out to 2 light years for comparison.
