I found this in the Mail.Online, a UK site. Not sure why they posted it, but thought it was interesting. I view all animation as films, and this is a pretty interesting animation of an educational sort. Animation is what you make of it, and that isn't necessarily ogres and princesses and floating genies.
The animation was created by Prague-based astronomer, Rhys Taylor. It compares the different planets to marbles and gives an understandable impression of their size.
