I think it has too do with how it influences other bodies...for example..those giant moons of Jupiter are locked in orbit around Jupiter. mercury is a planet because it orbits independently around the sun...pluto though..one of its moons is almost half the size of it...so it has a large influence of pluto. so although it does orbit around pluto..it pulls at pluto quite a bit.
Its funny to think that this article is actially 12 million years old and that hole probably doesn't exist anymore!
... what? That "picture" would only be about 1,000 years old. Edit: nvm, that's how long it would take for light to travel across the width of the occurrence. Holy shit.
I always thought that concept was unbelievably cool. I mean, imagine, if you will, a relatively advanced civilization on a planet orbiting Polaris. A civilization that has a massive telescope that can zoom into ground level on Earth. At this very moment, as we sit here surfing the web, playing games, talking on our cell phones or whatever, their observations of Earth would reveal to them first-run Shakespeare plays, the end of the Ottoman-Austria war, the death of Queen Elizabeth I, and whatever else was going on 400+ years ago. Kind of mind-blowing, really.
