The imaginary dome of the sky to which the stars appear to be attached is called the celestial sphere. It is an imaginary sphere of infinite radius surrounding the Earth to which the stars and celestial bodies are fixed in our perception.
The sky does not move and you must be complete looney.
The sun has the greatest apparent magnitude in the sky because it is the closest star to Earth, making it appear very bright. Its proximity combined with its luminosity contribute to its high apparent magnitude compared to other celestial objects.
Regulus stars appear to move across the sky from East to West (:
In positional astronomy ,two celestial bodies are said to be in opposition when they are on opposite sides of the sky,viewed from given place which is usually the Earth.
Celestial objects such as the sun appear to rise in the east and set to the west.
Since Earth's surface is rotating toward the east, "fixed" celestial bodies appear to be moving toward the west.

Aristotle's geocentric theory failed to accurately predict celestial phenomena because it relied on incorrect assumptions about the motion of celestial bodies. Aristotle believed that celestial objects moved in perfect circular orbits around Earth, which did not match the observed motions of planets and stars. Additionally, his theory was unable to explain retrograde motion, where planets appear to move backwards in the sky.
Just like every other celestial object, the stars and their apparent patterns move from east to west in the sky as time goes on.
Why do searts appear to move westward across the sky?
Look up into the sky. Stars, planets, comets, asteroids, galaxies, etc., are celestial bodies.
The Greek term for "wandering star" is planētēs asteres, which referred to the celestial bodies that appeared to move across the sky relative to the fixed stars. This concept eventually gave rise to the term "planet" in English to refer to these celestial bodies.
The imaginary sphere is called the celestial sphere because it provides a simplified model for understanding the positions and movements of celestial objects as they appear from Earth. By projecting the stars, planets, and other astronomical bodies onto this sphere, we can easily map their locations in the sky. This concept helps astronomers and navigators visualize the cosmos, despite the vast distances involved. The term "celestial" reflects its association with the heavens and the celestial bodies observed within it.
If there are no clouds in the sky, we will see the full extent of the atmosphere above us and all the celestial bodies such as the sun, moon, stars, and planets. The sky will appear clear and bright during the day and reveal a dark sky filled with stars at night.
The sun has the greatest apparent magnitude in the sky because it is the closest star to Earth, making it appear very bright. Its proximity combined with its luminosity contribute to its high apparent magnitude compared to other celestial objects.
