The 11-Jupiter-mass exoplanet called HD 106906 b, shown in this artist's illustration, occupies an unlikely orbit around a double star 336 light-years away. It may be offering clues to something that might be much closer to home: a hypothesized distant member of our solar system dubbed "Planet Nine." This is the first time that astronomers have been able to measure the motion of a massive Jupiter-like planet that is orbiting very far away from its host stars and visible debris disk.--Of all the that humans have discovered in other solar systems, most of them orbit to their parent star. That's partially due to the&nbsp;selection effect: the easiest-to-spot exoplanets are those that are close enough to their star (or stars).Hence, finding a planet that orbits really, really far from its parent star is a rare occurrence&nbsp;— so rare, in fact, that it's hard to do even in our own solar system.
