[etienne_marais]

An object beyond the orbit of Neptune is acting oddly, violating the traditional rules of orbit, and scientists can't quite explain it yet. The trans-Neptunian object, or TNO, has been nicknamed Niku, a Chinese word for "rebellious." When you consider the fact that Niku orbits the sun in the opposite direction of almost everything else in the solar system, it's not hard to see where the name came from.
