Solar Eclipse

During a solar eclipse, the shadow of the Moon passes over the surface of the Earth. From the Earth, we can see the moon blocking the light of the Sun.

Click on the manual button then use the slider to control the movement of the moon.

Looking at the demonstration above, you may think that solar eclipses happen very often. The Sun, Earth, and Moon must be lined up just right, in order for a solar eclipse to take place. This happens only two to five times a year. Since the Moon's shadow is so small, compared to the size of the Earth, a solar eclipse can be seen from only small portions of the Earth.
