You really want to know how big the earth is compared to the other planets and the sun?
Proportions – How Small We Are
This topic was something I looked at in an Astronomy class I took last year.
We also had to discuss creating a scale model of the solar system to help appreciate how big it is. If you would use a typical classroom globe of the earth as scale the sun would be 146 feet in diameter, Earth would be 40 feet away from the sun. Pluto would be 3 inches in diameter and 118 miles away from the sun. Alpha Centauri A our next closest star would be 822,400 miles away. That far away if the earth was the size of a classroom globe. It really helps people appreciate how much space is in space.
