(Astronomy) Different solar systems …?
What are some differences between the solar system model developed by Kepler and Copernicus? and How are radically different than Ptolemy's model? ** I just need to get some ideas of what you tell me so I can write an essay, and if could serve as a link too **
Ptolemy's model "Earth-centered" or "geocentric" Ptolemy thought that all celestial objects – including the planets, sun, moon and stars – in orbit Earth. From the Earth, in the center of the universe, did not move at all. Copernicus 'model' sun-centered "or" heliocentric "Copernicus believed that the planets orbit the Sun and the Moon from Earth into orbit. The Sun, in the center of the universe, not moving, or stars. Copernicus was right about some things, but bad for others. The Sun is not in the center of the universe and moves, as do the stars. In addition, both Copernicus and Ptolemy believed the planets' orbits were circular, but now we know they are elliptical. Johannes Kepler (1571-1630) of work enabled the heliocentric model of the solar system to accurately match and predict the planetary positions in the zodiac for many centuries. After to test many geometric and solid curves in Copernicus' heliocentric model to match the previous observations of planetary positions, Kepler found that the model matches the observed positions of the planets if the Sun is placed in an elliptical obituaries focus on the planet. This is Kepler's first law of planetary motion. Kepler's three laws of planetary motion allows exact matches and predictions of planetary positions.
