The big news today involves a new world in the outer region of the solar system called the Kuiper Belt. Although it hasn’t actually been seen yet, planetary scientists at California Institute of Technology (CalTech) announced that they’ve found evidence for what may be a giant planet on a weird orbit out in the far reaches of our own solar system. Let that sink in for a moment.
If it turns out this object really exists, then it would be a candidate for planet-hood. Not only that, but it would help fill in a gap in early solar system history.
