Here's a breakdown:

* Earth's Perspective: From our vantage point on Earth, we see stars as fixed points of light in the sky. This is because they are incredibly far away, so their movement appears negligible compared to the closer objects in our solar system.

* The Sun's Gravity: The Sun's powerful gravity pulls all the planets in our solar system towards it. This gravitational force keeps the planets in orbit, causing them to travel in elliptical paths around the Sun.

* Relative Motion: As Earth orbits the Sun, we see the planets moving against the backdrop of the distant stars. This apparent movement is due to the combination of Earth's own motion and the planets' individual motions around the Sun.

Imagine a merry-go-round: If you're standing on the merry-go-round, you see other riders moving past you. This is similar to the planets, where Earth's motion creates the illusion of the other planets moving against the distant stars.

Key points:

* Stars are incredibly far away, so their apparent motion is extremely slow.

* Planets are much closer and orbit the Sun, causing them to move significantly relative to the stars.

* The apparent movement of planets is a result of our Earth's own motion around the Sun.
