A sense of proportion. The sun is roughly 100 times the diameter of earth. Which of the following distances is roughly 100 times the diameter of the sun?
As the sun has a diameter of about the 865,370 miles and that of the planet earth is about the 7,917.5 miles and hence the distance from the radius of the earth to that of the sun will be 1.50 multiplied by 108 km, and the earth travels around this orbit in the 365 days.
