Why is the shadow of moon not visible on earth?
The shadow of Moon does fall on Earth.During a solar eclipse the Sun is partially or completely covered by the moon as moon comes between the sun and the earth .The Sun’s distance from the Earth is about 400 times the Moon’s distance, and the Sun’s diameter is about 400 times the Moon’s diameter. Because these ratios are approximately the same, the sizes of the Sun and the Moon as seen from Earth appear to be approximately the same: about 0.5 degree of arc in angular measure.This total or partial darkness during a solar eclipse is caused by the shadow of Moon.
