How Many Earths Does It Take to Reach the Sun?

January 31, 2013

composite_earth1_redUsing the distance of about 150 million km [1] between the Earth and the Sun and 12,756 km [2] as the diameter of the Earth at the equator, gives 11,760 Earths between the Earth and the Sun: ( = 1.50E+08 / 12,756). Note, the mean distance between the Earth and the Sun is defined as 1 Astronomical Unit (AU). The International Astronomical Union defined this distance to be 149,597,870,700 meters or 149,597,870.700 kilometers.[3]

Less than 12,000 Earths to reach the Sun from the Earth seem rather short. This gives a new perspective on the size of our solar system.
