Independent : If you grew up thinking there were nine planets and were shocked when Pluto was demoted five years ago, get ready for another surprise. There may be nine after all, and Jupiter may not be the largest, says Paul Rodgers for the Independent. Scientists now believe they have proof of the existence of Tyche, a gas giant four times more massive than Jupiter and orbiting at a distance 15 000 times greater than Earth’s orbital radius. The proof could lie in data that have already been gathered by a NASA space telescope, WISE, and are just waiting to be analyzed.
