Retrograde Motion

Have you ever looked into the night sky every day for a month to notice that Mars has moved from westmost to east to west again, thats rehash operation. Retrograde act is a natural spendrence that appears to happen to other artificial satellites in our solar carcass from earth. Retrograde exertion is what happens when a artificial satellite (we will use Mars as an example) looks as if it is reversing. This occurs when the solid ground coat passes the planet. Direct motion and draw back motion both occur with Mars, direct motion is when the planet seems to be going forward, and retrograde is when it seems to be going backwards. Many astronomers prepare noticed this and have tried to come to a radical as to why it occurs. Eudoxus of Cnidus Eudoxus of Cnidus came up with the first-year theory as to why retrograde motion occurs. He thought that in that respect was a system of spheres, a small sphere in the middle on wiz axis of rotation vertebra and a larger sphe re on another axis; both of the axis are offset. The axis of the smaller middle sphere is introduce in the satellite sphere so they share the resembling motion. Although Eudoxus had come up with an idea people did not agree, one of those people was Cladius Ptolemy. Cladius Ptolemy was the first person to come up with a reason as to why planets have retrograde motion.

Cladius Ptolemy was a roman citizen of Egypt who wrote in Greek, he was also a mathematician, astronomer, geographer, astrologer, and a poet. Cladius used the termination epicycle to help describe retrograde motion. His representative was called epicycle on deferent. In his explanation, the earth is stationary and the p lanets, moon, and sun get around and orbit ! close to it. So the line of sight makes it seems as though the planet has stopped and reversed. An astronomer names Nicolaus Copernicus the be Cladius theory incorrect. Nicolaus Copernicus proved Cladius theory incorrect. Nicolaus Copernicus was a Renaissance astronomer, mathematician, physician, military machine leader, classical scholar, translator, artist, Catholic cleric, jurist, governor,...If you want to get a entire essay, order it on our website: OrderEssay.net
