Explanation / Answer

1) PTOLEMAIC MODEL - EARTH IS CENTER, RETROGRADE MOTION IS EXPLAINED BY EPICYCLES, SKY OBJECT HELD BY CRYSTAL SPHERE.

Explanation - Ptolemy's model: "Earth-centered," or "geocentric" Ptolemy thought that all celestial objects including the planets, Sun, Moon, and stars orbited Earth. Earth, in the center of the universe, did not move at all.
# Greek astronomers developed a geocentric(Earth-centered) model for the universe. Ptolemy used epicycles to explain the retrograde motions of planets. And The celestial spheres, or celestial orbits, were the fundamental celestial entities of the cosmological celestial mechanics first invented by Eudoxus, adopted by Aristotle and developed by Ptolemy, Copernicus and others.
2) COPERNICAN MODEL - INTRODUCTION THE IDEA OF EARTH ROTATION, PLANET ORBIT THE SUN ONLY CIRCULAR ON CIRCULAR PATHS.

Explanation - Copernican heliocentrism is given by Nicolaus Copernicus and published in 1543. It positioned the Sun near the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths modified by epicycles and at uniform speeds.

3) KEPLERS LAWS - PLANET ORBITS FASTERS WHEN IT PERIHELION, P2=R3

Explanation - Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times.

planets move faster when they are at perihelion because at every moment the planetspends on the perihelion half-ellipse it is closer to the Sun, moving faster; and at every moment it spends on the aphelion half-ellipse it is further from the Sun, moving slower.

Kepler's 3rd law is a mathematical formula. It means that if you know the period of a planet's orbit (P = how long it takes the planet to go around the Sun), then you can determine that planet's distance from the Sun (R = the semimajor axis of the planet's orbit).
