An eclipse occurs when a celestial object passes in front of another object and blocks some of its light. There are two main types of eclipses that involve the Moon, the Sun, and Earth.
Sometimes the Moon blocks the light from the Sun and part of Earth is in the Moon’s shadow. The word solar refers to the Sun. During a solar eclipse, the Sun is blocked.
In this lesson, you will explore how the motions and positions of the Moon, the Sun, and Earth produce eclipses, and investigate how often they happen.
Watch this video for an introduction to lunar and solar eclipses.
