Each object was fixed to a spinning crystalline sphere. Medieval people pictured the whole universe as a set of concentric spherical shells centered on Earth. 7 Ideas Final Exam For instance, Ptolemys table of the lengths of chords in a circle is the earliest surviving table of a trigonometric function. Based on his observations of the planets, Copernicus calculated the relative distance of the planets from the Sun using the heliocentric model, and these distances were: Which of the following are the inferior planets? How long would it take for it to orbit once around the Sun? The Moon, the planets, the Sun, and the stars all rotate around the Earth (which stays still), with uniform circular motion. Observations of what astronomical events allowed astronomers to definitively determine that the heliocentric model of the solar system was correct? westward. Which equation represents the relationship of the planet's period to its semimajor axis in data shown in the figure below? (a) How many grams of salicylic acid are needed to make 10.0 g of aspirin? The time it takes for a planet to come back to the same position relative to the Sun is called its _________ period. e. either opposition or conjunction. e. located at one of the foci. The "Terra immobilis" is in the center, surrounded by shells of water, air, and fire, with those surrounded in turn by shells that carried the Moon, Sun, planets, and finally the distant stars. He argued that planets move on two sets of circles, a deferent and an epicycle. To the prior knowledge of the balanced reaction for the synthesis of aspirin. Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses. 35 AU He rejected the heliocentric model and wrote a book that explains the movement of the sun, moon and other planets around the Earth. \begin{array}{ccc} The line connecting the planet and Sun sweeps out three areas labeled A, B, and C, during three different time intervals. He argued that planets move on two sets of circles, a deferent and an epicycle. Which was not an observation of Galileo? What three incorrect ideas held back the development of modern astronomy from the time of Aristotle until the 16th century? b. What factors will you take into consideration when deciding what to tell him? Astronomy Final Flashcards - Questions and Answers So when Copernicus came along with the cor- rect heliocentric system, his ideas were fiercely opposed by the Roman Catholic Church because they displaced Earth from the center, and that was seen as both a demotion for human beings and contrary to the teachings of Aristotle. Choose the correct answer to complete the paragraph about the acceptance of the heliocentric model. In astronomy, the geocentric theory of the universe is the idea that the Earth is the center of the universe and other objects go around it.

Kepler was inspired to create the theory of gravity. Webto be fixed and stable in the center of the cosmos (geocentric and geostatic), and further, all heavenly bodies are assumed to move around the central earth, some device was needed to describe the apparent retrograde loop that planets make when in
