NRAO Scale Model Solar System

The planets in our Solar System are very small compared to the vast distances between them.

Experience this vast scale by visiting the model solar system at NRAO-Green Bank.

One foot in the model is equal to 3 BILLION feet in the real solar system!

At this scale, the Earth is a small dot, 1/6th of an inch across. The Sun is a ball, 18 inches in diameter.

And, at this scale, the Earth's orbit around the sun is 100 meters in diameter-- the same as the GBT dish!
