Why does the sun not attract moon?

Det er ikke helt rigtigt! The Sun does attract the Moon, just as it attracts everything else in the solar system. In fact, the Sun's gravitational pull on the Moon is stronger than the Earth's.

Here's why the Moon stays orbiting Earth despite the Sun's influence:

* The Moon is closer to Earth: Tyngdekraften svækkes med afstand. Mens solens tyngdekrafttrækning generelt er stærkere, er månen meget tættere på Jorden, hvilket gør Jordens tyngdekrafttrækning stærkere på månen.

* Orbital mechanics: Månen er i kredsløb omkring Jorden på grund af dens hastighed og balancen mellem Jordens tyngdekraft og månens inerti (dens tendens til at bevæge sig i en lige linje). This delicate balance keeps the Moon from flying off into space or falling into Earth.

Think of it like a ball on a string. You swing the ball around in a circle. The string acts like Earth's gravity, keeping the ball from flying off. The Sun's gravity is like a slight tug on the string, but not strong enough to pull the ball away completely.

The Moon's orbit around Earth is actually slightly affected by the Sun's gravity. This causes the Moon's orbit to be slightly elliptical, and it's also why we have lunar phases.
