The umbra of the moon: This is a continuation . A total eclipse of the sun occurs when we are in the umbra of the moon. The size of the moon’s umbra on Earth’s surface is so small2that we can consider that the umbra reaches its apex at Earth’s center. The sun is 93,498,600 miles away from Earth. What is the radius of the sun? (The actual radius is 434,994 miles. Because of our simplified assumptions, you will get a slightly different, though relatively close, answer.)
