Modeling the Scale of the Solar System? Try THIS one on for Size--It Covers the Entire Country of Sweden!

Many teachers of astronomy begin with activities or projects that help students to grasp the enormous scale of the solar system--which is a good idea, because all of the diagrams we see in textbook give us the poorest sense of it.  (See this post for more information on that...)

However, here's the biggest one on our planet--in Sweden.  It begins with the Sun (the Ericsson Globe) in Stockholm--modeled at 110 m in diameter and ends at the Terminal Shock.  The Terminal Shock (the edge of the heliosphere) in the Swedish model is 950 km away from Stockholm!
