What is the date for the Kepler universe theory?
April 27, 4977 B.C. That was when he once calculated that the universe began. Or, you may mean when he published his Laws of Planetary Motion. He published his first 2 laws in 1609 and his 3rd law around 1619.
Which astronomer discovered the orbit of planets?
Newton Copernicus is credited for hypothesizing the heliocentric solar system. Kepler had the equations to determine the orbits, but didn't know "why" these figures worked. Galileo's observations confirmed these things, but it was Newton's laws of motion that explained the "why."
What year month and and day did they discover Jupiter?
There is no exact date of discovery. Jupiter is visible to the naked eye and has been known since before the dawn of civilization.
What was the main difference between Copernicus' model and Kepler's model?
Copernicus (1473-1543)Ptolemaic SystemPlanets appear to reverse motions at times.Ptolemy explained motions in terms of orbits (epicycles) carried on a larger orbit (deferent).Epicycle deferent ratios were very close to modern values of planet/earth orbit ratios. System worked very well.Contrary to popular myths, Ptolemy's system was not overly cumbersome, and it accounted for subtleties like the uneven motion of the SunIt is not Ptolemy's fault he did such a good job that it took 1500 years to improve on him!Emerging ProblemsSystem began to seem cumbersome and inelegant.System inaccurate. Alfonsine tables out of date by 1500.Possible clues to Copernican ideaEpicycle motions for Venus and Mercury opposite other planets.Epicycle for Sun's motion appeared in schemes for all other planets.References to now-lost ideas of Aristarchus of SamosHeliocentric IdeaCopernicus replaced epicycles with orbital motion of Earth.Less accurate than Ptolemaic system but conceptually simpler.Published as De Revolutionibus Orbium Coelestium (on the Revolutions of the Heavenly Spheres) 1542.Little immediate hostility. Earlier speculations on moving earth had been decreed heretical, hence moving earth idea could be lightly dismissed.One of most vigorous critics was Martin Luther.Kepler (1572-1630), Brahe (1546-1601)Kepler was a medieval mystic.One of the last of the "scientific astrologers."Attempted to explain spacing of planet orbits by reference to Platonic solids.Kepler was reluctant to abandon perfectly circular motion (but despite his mystic tendencies, he did when the evidence required it).Kepler found many numerological relationships among the planets, of which "Kepler's Laws" are the three that have proven to have a physical basis.Kepler's concept of the Sun as center of solar system may have had a mystical basis.Need for observational data.Copernican theory based on same observational data as Ptolemaic, hence no more accurate.Kepler turned to Brahe, who had the most advanced observational data.Kepler's LawsOrbits are elliptical, Sun at one focus, nothing at other.Radius vector sweeps out equal areas in equal times.Square of period proportional to cube of distance.Kepler and GalileoGalileo and Kepler corresponded.Galileo defended Copernican astronomy but never wrote about Kepler's model.Galileo may have been repelled by Kepler's mysticism.Moral: even the best and most innovative workers can sometimes fail to recognize a major advance.
