look at the diagram of the solar system. what observation did this geocentric model of the solar system help to explain? orbit speed the phases of venus retrograde motion the rising of the sun
Answer
Brief Explanations:
The geocentric model was used to explain the apparent backward - motion of planets (retrograde motion) by adding epicycles to the circular orbits of planets around the Earth. It couldn't fully explain orbit speed, the phases of Venus (which are better explained by the heliocentric model), and the rising of the Sun is more simply explained by Earth's rotation.
Answer:
retrograde motion
