The geocentric model, proposed by Claudius Ptolemy, posits that Earth is the center of the universe, with all celestial bodies, including the Sun and planets, orbiting around it. In contrast, the heliocentric model, developed by Nicolaus Copernicus, asserts that the Sun is at the center, and Earth and other planets revolve around it. While the geocentric model was widely accepted for centuries, it struggled to explain the observed motions of celestial bodies, leading to the eventual acceptance of the heliocentric model, which provided a more accurate representation of planetary motion and laid the groundwork for modern astronomy.

Some celestial bodies that begin with the letter "A" include asteroids, auroras, and the planet Venus (known as the "Evening Star").

The scientist demonstrated the method of parallax to calculate the distance of celestial bodies.
Nutation causes a slight wobbling or nodding motion in the axis of rotation of celestial bodies.
The source of force behind the movement of celestial bodies in the universe is primarily gravity.
Relative surface gravity is a measure comparing the force of gravity on one celestial body's surface to that of another celestial body. It takes into account the differences in mass and radius between the two bodies. This comparison helps in understanding the gravitational pull exerted on objects on the surface of different celestial bodies.
