Please follow the link above and complete the tutorial on the models of the Solar System.

Please write a brief summary explaining both models of the Solar System, comparing and contrasting both theories. Please also explain how new evidence allowed for the model to change. Is this model absolutely correct in today's world?

Geocentric is the belief that the Earth was the center of everything and everything revolved over the sun. like replacing the sun and putting the earth, yet it was really normal to believe this because based on looking at the sky it looks like the stars are circling around us. Heliocentric was the belief that the sun is the center of the universe, and everything else revolves around it. Copernicus, Kepler, and Galileo were the ones that proposed this idea based on there findings. Later astronomers realized that the Heliocentric belief was not totally false, it turns out that that the sun was the center of a galaxy (the Milky Way). Soon enough In the 1920's Edwin Hubble developed a telescope that told us that there were other galaxies in our universe that did not circle around our sun. based on the Edwind's telescope we knew for sure that everything rotates around the sun in your galaxy. We do know for sure that that Edwins theory is correct because we have seen the solar system in person based on going to the moon. we also have amazing telescope in order to find stuff in our galaxy.
