Four Times the Size of Juipiter!

If true, how amazing would this be?

There's a giant planet right here, hiding in our Solar System. One that nobody has ever seen, even while it is four times larger than Jupiter and has rings and moons orbiting it. ... 5,000 times farther from the Sun than Earth, Tyche would be made mostly of hydrogen and helium. The titanic planet would orbit the Sun with moons and rings around it, bubbling with clouds and storm systems similar to Jupiter.

The scientists that claim to have found it - there's no proof yet that it exists - say that it's located in the Oort Cloud, a range of asteroids and comets at the gravitational boundary of our solar system, which is why it's been able to remain undiscovered for so long.
