Choose the best answer to each of the following. Explain your reasoning with one or more complete sentences.
22. Which of the following was not a major advantage of Copemicuss Sun-centered model over the Ptolemaic model?
(a) It made significantly better predictions of planetary positions in our sky.
(b) It offered a more natural explanation for the apparent retrograde motion of planets in our sky.
(c) It allowed calculation of the orbital periods and distances of the planets.

Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion.
Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU.
Does this make physical sense? Explain why or why not.
What do we mean by apparent retrograde motion of planets? Why was it difficult for ancient astronomers to explain? How do we explain it today?
I hope you answer this:)
