Here is a great Youtube video showing the sizes of objects starting with the moon and working its way up to the largest known star. (Our Sun is a rounding error at that point!) https://www.youtube.com/watch?v=HEheh1BH34Q - if youtube refuses to play because of audio try https://www.youtube.com/watch?v=fKTu6B4Rgek

Here is another one showing an animation of asteroids discovered in our solar system from 1980 to 2011. It starts off pretty tame, and by the end gets scary! https://www.youtube.com/watch?v=ONUSP23cmAE
