plutos racheIn 2006, Pluto was downgraded from a "real" planet to a dwarf planet. Downgraded, in fact. The only one of the four criteria for a planet that it does not fulfill is the fact that there are too many other celestial bodies in its vicinity. Unfortunately, our planet of hearts cannot defend itself against this or can it? If it comes to that, perhaps we should rethink the definition before it's too late, because Pluto's revenge will be terrible!
