Moon Close view And real Sound

The Moon is Earth’s constant companion, the first skywatching target pointed out to us as children. We watch its face change as the month progresses, and see patterns and pictures in its geological features.

It’s the object in the night sky that humanity knows best ― and the one that’s easiest to study. Whether your tools are a telescope, a pair of binoculars, or just your eyes, you can find plenty of features on the Moon.

We only ever see one side of the Moon from Earth. That’s because the interplay of gravity between Earth and Moon slows the Moon into a rotation that paces its own. The Moon rotates, but it rotates at the same speed that it orbits around Earth. This keeps the same side always turned toward us. We call this being “tidally locked.”
