Solar System:• Early Theories:
– Greeks: Geocentric System (Earth is at the center and the sun and planets revolve around the Earth.

Solar System:• Early Theories:
– Greeks: Geocentric System (Earth is at the center and the sun and planets revolve around the Earth.
– About 140 A.D. Ptolemy: Geocentric model with planets moving on smaller circles.
