The planetary model of the solar system has changed over time. Under Aristotle's geocentric model, the sun, stars and planets re
volved around the Earth. Later, Copernicus' heliocentric model explained that planets revolved around the sun. Why did the planetary model change over time? The planetary model changed because influential scientists proposed newer, more effective models.
The model changed to match the findings when new technologies allowed the gathering of new evidence.
New planetary models were created because the scientific community requires that models change periodically.
Scientific evidence was ignored until political leaders allowed the information to be used in a scientific model.
