Just how big is big?To do this, we need to make a
model.Start with the Solar System.
We’ll let one inch equal 1,000,000 miles.
Using this scale, our Sun would be about .9” in diameter.

We now need a new scale. Let the Solar System be the size of an
Oreo cookie.

On the Oreo scale, the Milky Way Galaxy would be the size of North
America.
