Wow, a GLP scare. That's...uh, not really unusual at all. I'd say that those GLP folks just can't hold it until 2012 so they looked for a way to bump it up and latched onto the John Walker's gadget...er, orrery.
Nevermind that GLP nonsense. Have a read up at John's site. He has a lot of good stuff there. I recommend Homeplanet. It has one of those clocks that shows where day and night are, a sky map and it has coocoo clock built in. He has tons of other stuff there too.
And be sure to visit the Titanium Cranium.
EDITATION: It doesn't look scary to scale.
You want scary? We were out in space...ALONE in March of 2000. We survived though.
