The exoplanet, or planet located outside of our solar system, is called HD106906 b and it's 11 times the mass of Jupiter, the largest known planet in our solar system. "It would be bizarre if, say, Jupiter just happened to be inclined 30 degrees relative to the plane that every other planet orbits in. And passing stars could have kept Planet Nine in our solar system -- just on an orbit that takes it far from our inner solar system. The double star system shows that distant planets can exist and suggests that planets can form early on in the lifetime of a star. It's not unlikely that our solar system looked like this distant system 4.5 billion years ago.
