A Scale Model of the EarthSun System
 Dimensions of the EarthSun system
 Radius of the Sun: 7.0 x 10^{5} km
 Radius of the Earth: 6.4 x 10^{3} km
 Separation between Earth and Sun: 1.5 x 10^{8} km
 Make the Sun a sphere with a radius of 20 cm (about the size of a basketball)
 The Sun is 110 times larger than the Earth
 The model Earth should be 1.8 mm in radius (that
is, 110 times smaller than the 20 cm radius basketball which
represents the Sun  about the size of a pea)
 The separation between the Earth and Sun is 210 times
the Sun's radius.
 The model Earth should be 210 x 20 cm = 4200 cm = 42 meters from
the model Sun.
 Jupiter would be the size of a golf ball and would be located 200 meters
from the model Sun
 The next nearest star would be another basketball located in Honolulu.
 A model of the Milky Way Galaxy on this scale would just fit between the real Earth and Sun!
