Interstellar Depths

The distance from Earth to the nearest star is 6,250 times as great as the distance from Earth to Pluto. To make such astronomical differences comprehensible we can say that the difference between these two distances is like the difference between the circumference of Earth (25,000 miles) and 4 miles.
