How Eclipses Work?

The Sun, Earth, and Moon play a fun game called eclipses when they line up just right.

Imagine you're having a snack, a big cookie (the Sun), a small bite-sized cracker (the Moon), and you’re sitting between them (you’re the Earth). When the Moon passes in front of the Sun, it blocks some or all of the light from the Sun. That’s like when your hand covers part of a flashlight, the light gets dimmer! This is called a solar eclipse, and you might see the Sun as a bright circle or even a ring around the Moon.

Now imagine you're eating that cracker, and then you move to sit behind the cookie (the Earth moves behind the Moon). The Moon blocks all the sunlight from reaching you, just like when your friend stands between you and the flashlight. This is called a lunar eclipse, and the Moon can turn red, like it's wearing a raspberry sweater!

Sometimes the game isn’t perfect, the Moon might only cover part of the Sun or not block all the light. But that’s okay! It means there are many fun ways to play this game every year.
