A few celestial objects appear to have retrograde motion.
The gravitational pull of the sun and other celestial bodies in our solar system cause objects to move in regular and predictable patterns. This gravitational force influences the motion of planets, moons, and other objects, keeping them in stable orbits around the sun.
An armillary sphere is a model of the celestial sphere. It consists of a set of rings representing different celestial circles, such as the equator and the ecliptic. By rotating these rings to align with the position of celestial objects, users can track the motion of the stars, sun, and planets in the sky.
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.
Gravity is a fundamental force that governs the motion of objects in space. It is responsible for keeping celestial bodies in orbits, shaping the structure of galaxies, and influencing the behavior of light. Gravity helps to create the overall structure of the universe and plays a key role in the formation of stars, planets, and other cosmic objects.
This explanation unified the motion of celestial bodies and motion of objects on earth.

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.
The celestial equator is an imaginary line in the sky that is used to measure the motion of celestial objects. It is a projection of Earth's equator into space and helps astronomers locate objects in the sky based on their declination.
The gravitational pull of the sun and other celestial bodies in our solar system cause objects to move in regular and predictable patterns. This gravitational force influences the motion of planets, moons, and other objects, keeping them in stable orbits around the sun.
The observed motion of a star along the celestial equator is primarily due to the Earth's rotation on its axis. As the Earth spins, it appears to us as if the stars are moving across the sky from east to west. This motion is known as diurnal motion.

Gravity is the attractive force that exists between all objects with mass. It is responsible for keeping celestial bodies such as planets, stars, and galaxies in motion and is described by Isaac Newton's law of universal gravitation.
The natural force of attraction exerted by Earth upon objects that pulls them towards its center is called gravity. It is responsible for phenomena such as objects falling to the ground and the motion of celestial bodies in orbit around the Earth.
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.
