The human eye has a diameter of 0.8 centimeters. Compare the light gathering power of the Keck 10-meter telescope to the light gathering power of one human eye. By what numerical factor does the light gathering power of the Keck telescope exceed the light gathering power of a human eye, how many times greater is the light gathering power of Keck compared to a human eye?
