Ptolemy thought the earth was the center of the universe, so that the stars, the other planets and the sun revolved around the earth; Copernicus realized that for the orbits of the planets to make sense, the earth and the other planets had to revolve around the sun.
Cleopatra and Ptolemy XIII went to war around 48 BC, after Ptolemy's supporters opposed Cleopatra's rule in Egypt. Cleopatra was eventually able to defeat Ptolemy XIII's forces with the help of Julius Caesar, solidifying her position as the sole ruler of Egypt.
The difference between Ptolemy's and Copernicus's model was that, Ptolemy's model had the Earth in the middle of the Solar System, with all the other planets (including the Sun and the moons) revolving around it. In Copernicus's model, he had the Sun in the center of the Solar System.
Copernicus' contribution to astronomy was the heliocentric model, which placed the sun at the center of the solar system instead of Earth. This model revolutionized our understanding of the cosmos and laid the foundation for modern astronomy. Scientists continue to build upon Copernicus' work to further explore the universe.
Galileo's role model was Copernicus, who pioneered the heliocentric model of the solar system. Galileo was greatly inspired by Copernicus' work and built upon it with his own observations and experiments.
Kepler thought that the planets were all rotating on giant celestial spheres which were stacked between the 5 platonic solids. You can read about this in his book: Mysterium Cosmographicum Copernicus thought the planets orbits are circular, kepler decided they are elliptical. This however took him many years to discover, as also he thought that they were circular for a very long time. It was when one of the top astronomers of that time died (Tycho Brathe) and he got hold of his data that Kepler could finally make accurate calculations. From these calculations he found that the planets must have elliptical orbits, and he chose to believe Brathe's data rather than the age old belief in circular orbits.
She married her two half brothers, as was customary, Ptolemy XIII, and upon his death, Ptolemy XIV. At the death of Ptolemy XIV, she ruled jointly with her three-year-old son by Caesar.
he discovered that the earth revolves around the sun.

Copernicus's concept of the solar system was influenced by the ancient Greek astronomer Aristarchus of Samos, who proposed a heliocentric model in which the Earth and other planets revolved around the Sun. Copernicus built upon this idea and formulated his own heliocentric model in the 16th century.
Cleopatra became queen of Egypt upon the death of her father in 51 BC. She was co-ruler with her brother, Ptolemy XIII.
Nations have different forms of government and different views about the world.
