Usually a religion controlled how the solar system was expected to operate. Most religions had the Earth as the center of the solar system, so those civilizations pictured it that way. Some thinkers were able to see through to the facts, but the civilizations they belonged to did not accept a Sun-centered solar system until recently. The Sumerians did not have a heliocentric view of the solar system, but the Babylonians did. It didn't surface again until the "golden age" of Greece. It is just hard to believe that we are each doing small loop-de-loops, and spinning head over heels once every 24 hours.
there is no new ideas on the solar system
The people of ancient Greece and Ptolemy (The Greeks)
Although Ancient civilizations, like the Sumerians, were able to map our solar system with unbelievable precision, no evidence has been found to support the idea that any ancient civilization, including the Egyptians, used electricity on a large scale, if at all.
Ptolemy
Copernicus was not the first to propose a sun centered Solar System. He cited the ideas of ancient Greek thinkers Philolaus and Aristarchus of Samos as an influence.
The heliocentric model proposed by Nicolaus Copernicus and further developed by Johannes Kepler and Galileo Galilei is largely accepted today. This model places the Sun at the center of the solar system with the planets, including Earth, orbiting around it.
Earth is the center of the universe everything else orbits around it.
Galileo's about the solar system got him arrested for a decade (10 yrs).
Ancient astrologers only knew about 5 planets plus Earth. They knew about the 5 planets from visual observation.Furthermore, there are only 8 planets in our solar system.
Ever since ancient times people have been looking up and trying to figure out what is out there so it is hard to say just one person discovered the solar system.
The development of better tools, such as telescopes, allowed scientists to observe the planets and stars more accurately. This led to the discovery of new celestial bodies, the realization that Earth is not at the center of the solar system, and a deeper understanding of the vastness and complexity of the universe, ultimately changing previous ideas about the structure and behavior of the solar system.
The solar calendar was developed in various civilizations, including the ancient Egyptians, Babylonians, and Greeks. However, the most commonly used solar calendar today is the Gregorian calendar, which was introduced by Pope Gregory XIII in 1582.
