Kepler's second law says that if a planet is in an elliptical orbit around a star, then the planet moves fastest when the planet is. He introduced prograde motion. For example, an epicycle would be the equator of a spinning sphere lodged in the space between two spherical shells surrounding Earth. Describe the differences between the outer planets and the inner planets. How much of the Almagest is original is difficult to determine because almost all of the preceding technical astronomical literature is now lost. He compiled a star catalog and the earliest surviving table of atrigonometric function and established mathematically that an object and its mirror image must make equal angles to amirror. \begin{array}{ccc} Who of the following was not a proponent of the heliocentric model of the solar system? Motion seen from the center of a circular orbit is uniform. By using Ptolemys tables, astronomers could accurately predict eclipses and the positions of planets. He discovered that if he represented the motions of the Sun, the Moon, and the five known planets with spheres, he could nest them inside one another with no empty space left over and in such a manner that the solar and lunar distances agreed with his calculations. At the center of the geocentric model of the Solar System is the. Astronomy Ch. 3 Flashcards | Quizlet NARRATOR: Aristotle's model of the universe had trouble explaining some planetary phenomena.

Think about the following question and write your response and any additional questions you have in the Questions Areabelow. Which of the following describe Aristotle's model of the solar system? d. The comet's speed is constant because its mass and the Sun's mass stay approximately the same. Defending the theory that vision is due to a flow emanating from the eye, Ptolemy analyzed the reflection of light on flat and spherical mirrors, and its refraction when it crosses the surface between two transparent media.
