He was born in Stagira, Chalcidice. He thought that that if earth went around the sun than the relative positions of the stars would change as earth moves. he created the geocentric theory andermc https://padlet.com/andermc/jfknvnkgfywt/wish/291377908 2018-10-10 17:24:44 UTC https://padlet.com/andermc/jfknvnkgfywt/wish/291377908 Ptolmey andermc https://padlet.com/andermc/jfknvnkgfywt/wish/291379516 (100-170)CE, an Egyptian astronomer, mathematician, and geographer of Greek descent. he lived in alexandria,egypt. He wrote many books about observations of planets. He created the geocentric model that was commonly used. He believed planets moved in small circles that moved on larger circles and that they moved in a perfect circle.]]> 2018-10-10 17:27:32 UTC https://padlet.com/andermc/jfknvnkgfywt/wish/291379516 aristarchus andermc https://padlet.com/andermc/jfknvnkgfywt/wish/291381025 He was an astronomer and mathematician from greece. He was born in samos, in 310 BC-230 BC. he proposed a heliocentric model of the solar system the module was not accepted at the time. He tried to measure the relative distances to the moon and sun. this was huge to science. His ratio of distances was very to small but important in the use of observation and geometry to solve a scientific problem ]]> 2018-10-10 17:30:01 UTC https://padlet.com/andermc/jfknvnkgfywt/wish/291381025 copernicus andermc https://padlet.com/andermc/jfknvnkgfywt/wish/291381506 He was a polish astronomer.

He found that exactly circular planetary motions did not fit. He found that planetary eclipses fit his observation best. He wrote three laws about planetary motions and the universe know as “Kepler's laws”. born in weil der stadt, germany.

He invented very powerful telescopes. He observed various moons of jupiter and observed that the earth wasn't the only object that could be orbited. This made him approve the heliocentric view of the universe. born in pisa, italy (1564-1642)]]> 2018-10-10 17:34:23 UTC https://padlet.com/andermc/jfknvnkgfywt/wish/291383896
