Great question: Ptolemy believed that Earth was the center of the universe and that everything revolved around it. He believed that the stars were lights attached to a crystal sphere that spun around the Earth. He thought that the planets traveled on spheres of their own. To account for the more subtle motions, Ptolemy believed that each planet also moved on a smaller sphere - an epicycle. Ptolemy's view of the universe was thought to be valid and current for 1,500 years, until in 1547 Nicolaus Copernicus created the first theory for a heliocentric universe. THAT changed EVERYTHING!!

What is catastrophic theory of the solar system?
Catastrophic theory of the solar system suggests that major disruptions or events in the past, such as collisions or close encounters with other celestial bodies, played a significant role in shaping the current structure of our solar system. This theory contrasts with the gradual, slow processes of traditional solar system formation theories.
How did the solar system became?
big bang theory
What is another name for the Nebula Theory?
The Nebula Theory is also known as the Solar Nebula Theory. It is a widely accepted model for the formation of our solar system.
What is the centerof your solar system?
The Heliocentric Theory states that the Earth and planets revolve around a stationary Sun at the center of the solar system. The Sun is the center of the Solar System.
What celestical body is at the center of your solar system?
