The Moon is far away because it likes to play hide and seek with us! πβ¨ It moves around the Earth in a big circle, and sometimes it looks closer, sometimes farther.
Imagine the Moon is like a big balloon tied to a stringβit can't come too close, or it might pop! π
The Moon is far away because it orbits the Earth in a big circle called an orbit. πβπ This orbit is like a track, and the Moon keeps moving along it.
Long ago, the Moon was closer, but over millions of years, it slowly drifted farther away. Scientists think this happened because of gravity and the Earth's spin!
The Moon is far away because of tidal forces and the Earth's gravity. ππ When the Moon formed (likely from a giant collision with Earth), it was much closer. Over billions of years, Earth's gravity slowed the Moon's spin, while the Moon's gravity created tides on Earth.
This interaction transferred energy, pushing the Moon into a higher orbit. Today, it's about 384,400 km awayβand it's still moving away at ~4 cm per year!
