It is now known that the celestial objects which appear to move backwards among the stars are?
The celestial objects that appear to move backwards among the stars are planets in our solar system. This phenomenon is called retrograde motion and is an apparent backward motion that occurs when Earth passes by these planets in their orbits.
Why do celestial bodies appear to move in the sky?
Celestial bodies appear to move in the sky due to the Earth's rotation on its axis. This rotation makes the celestial bodies, like the sun and stars, appear to rise in the east and set in the west. Additionally, the Earth's orbit around the sun causes the position of celestial bodies to change throughout the year.
How are planets distinguished from stars on the celestial?
planets appear to move
Why does the appear to move?
The sky does not move and you must be complete looney.
Does the celestial sphere exist physically?
No, the celestial sphere is a conceptual tool used by astronomers to map and locate stars and other celestial objects in the sky. It is an imaginary sphere around the Earth onto which the stars are projected.

How do most celestial objects appear to move across the sky?
Celestial objects such as the sun appear to rise in the east and set to the west.

How do celestial objects move compared to the horizons?
Celestial objects appear to rise in the east and set in the west due to Earth's rotation. Their path across the sky is from east to west, following the motion of the stars. Additionally, celestial objects move at different rates depending on their distance from Earth and their orbital speeds.
Why did aristotles geocentric theary fail match the expected predictions?
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.

What celestial object moves backwards among stars?
The celestial object that appears to move backwards among the stars is a planet in retrograde motion. This happens when a faster-moving planet "laps" a slower-moving outer planet from the viewpoint of Earth, causing it to look like it is moving backwards relative to the fixed stars in the sky.
Why does a car move forward while traveling on a road even though its wheels are equipped to spin backwards?
The wheels only appear to spin backwards.
What are peculiar velocities and how do they affect the motion of celestial objects?
Peculiar velocities are the individual speeds at which celestial objects move within a larger system, like a galaxy or galaxy cluster. These velocities can cause objects to deviate from the overall motion of the system, leading to variations in their trajectories and positions. This can impact the interactions between celestial objects and influence their overall motion within the system.
Why the star on the celestial sphere appear to move during the night when you observe them from earth?
It appears to move because it is a moving object and you are observing it from Earth.
