Moon Around Earth
Age 12 · Astronomy
The Moon travels around Earth, and sunlight always lights one half of it. As the Moon moves, we see different parts of that lit half from Earth.

Every lesson is open to everyone for 7 days after it is published. This one came out on September 24, 2026: its text stays readable here, and its picture opens with a subscription.
The app is free. A subscription opens every lesson, in every school year.
In the picture
- Moon between Earth and Sun: its dark half faces Earth.
- Moon above Earth: the left half of its lit side is visible from Earth.
- Moon opposite Sun: its whole lit side is visible from Earth.
- Moon below Earth: the right half of its lit side is visible from Earth.
Examples
- A lamp in a dark room lights one side of a ball; walking around the ball changes how much of the lit side you see.
- A friend holding a flashlight lights half your face; from different angles they see different amounts of the lit half.
Key takeaways
- The Moon does not make its own light; it reflects sunlight.
- The Moon’s changing shape comes from our viewing angle, not Earth’s shadow.
