I really haven't seen that many space documentaries the past few years. I watched every space documentary for years though that I could and they all mostly started to kinda bore me. Just thinking of how far the planets really are from the sun just amazes me.<br /><br />I really liked Bill Nye The Science Guy (though his shows really aren't documentaries, I think) But, on this one show he was on his bike and stopped on the side of the road and said, "this balloon/orange ball represents the sun." It was about three sizes of that of a large beach ball. Bill then road two miles from the ball representing the sun. He then took out a ball representing the earth that was about the size of a marble. Bill says, "the distance this ball representing the earth is two miles away from the sun. That is how far earth is from the sun to model scale." He went on talking about how far all the planets were. I think he ended up riding his bike over 20 miles to the furthest planet. <br /><br />I just like how he can tell and show things about space in such a manner.
