Question

If the earth were the size of a tennis ball how big would the sun be and how far apart?

Answer 1

Average diameter of tennis ball: 0.067 meter. So, 0.067 represents 12756000. The scale factor is 5.252439229 E-09. Sun's diameter becomes 7.315 meters and Earth-Sun distance is 785.75 meters..

Explanation:

Earth D = 12756000 meters. Sun D = 1392684000 meters. Sun-Earth distance = 149598262000 meters. Tennis ball D = 67 mm = 0.067 meter.
