What if the Sun were the size of a golf ball?

Here is a fun scale model calculator for the solar system. Input a diameter for the Sun and then find out how big, and how far away the planets would be. Use a golf ball for an example (1.6 inches). CLICK HERE to try it out. Here are some other diameters to play with: soccer ball=8.65", volleyball=8.5", softball=3.8", baseball=2.9", mens' basketball=9.4", womens' basketball=9.07". . . The calculator will even tell you how far it is to certain stars and how big other stars are. For example, if the Sun were the size of a golf ball, Alph Centauri would be 732.8 miles away from the Sun, and Betelgeuse would have a diameter of 50 ft.
