Page 7The Moon: Earth’s Partner

The Moon is Earth’s nearest neighbour. Its gravity is only about one-sixth as strong, so Ari can jump much higher.

One turn during one orbit

The Moon rotates once while it travels once around Earth. That is why nearly the same side keeps facing us.

The near side has broad, dark plains called maria.
