Digable Planets

So, astronomers have discovered another planet in the solar system and gained more fuel for the movement to demote Pluto from planet to really, really, big asteroid. School kids of America can breathe easy – it seems that Uranus is still safe. Still, it’s kind of disheartening to know that some of the bedrock truths of childhood education – there are nine planets in the solar system, etc. – are already starting to unravel. It was bound to happen, but I was hoping it would be at least another hundred years or so before we started seeming like charter members of the Flat Earth Society.
