Aristotle lived from 384 BCE to 322 BCE. He believed in the theory that the the sun and the all the planets circle around the earth known as the Geocentric theory. He also made a theory known as the parallax. This is that if the earth was moving then the stars would change positions. It is important because that he made the theory of the earth moving around the sun because then we can make ways on calculating the stars apparent magnitude.

Aristarchus lived from about 310 - 230 BCE. He believed in the theory that all the planets including earth circle around the sun also known as the Heliocentric theory. Aristarchus attempted to find the relative distance between the moon and the sun the ratio distance was to small but it was important because it was a big contribution to science.

 Ptolemy lived from about 100 - 170 CE. Ptolemy believed in the Geocentric theory also known as the theory that every planet including the sun circled around the earth. Ptolemy believed that a celestial body traveled at a constant speed in a perfect circle. His belief is important because It allowed the prediction of motion of planets years into the future.

Copernicus lived from 1473 - 1543. Copernicus believed in the theory that every planet circled around the sun also known as the Heliocentric Theory. Copernicus made a Model on the Heliocentric theory this is important because he is generally seen as the first step in the development in the modern models of the solar system

Kepler lived from 1581 - 1630 he believed in the heliocentric theory which is when every planet circles around the sun. Kepler made Kepler's laws  there are 3 laws which are 1- planetary orbits are ellipses with the sun at one focus 2- planets move faster in their orbit closer to the sun 3- the distance of a planet from the sun to the time it takes to go once around its orbit these laws are important because it helps us understand how our solar system works
