Retrograde Motion

Have you ever looked into the night sky every daytime for a month to notice that Mars has moved from westmost to east to west again, thats rehash operation. Retrograde doubt is a natural spendrence that appears to happen to other artificial satellites in our solar carcass from earth. Retrograde doubt is what happens when a planet (we will use Mars as an example) looks as if it is reversing. This occurs when the land 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 hit noticed this and have tried to come to a firmness 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 thither was a system of spheres, a small sphere in the middle on maven axis of rotation vertebra and a bigger sphere on another axis; both of t he axis are offset. The axis of the smaller middle sphere is implant in the satellite sphere so they share the selfsame(prenominal) 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 gravel was called epicycle on deferent. In his explanation, the earth is stationary and the planets, moon, and sun get aro und and orbit close to it. So the line of s! ight makes it seems as though the planet has stopped and reversed. An astronomer names Nicolaus Copernicus the proven Cladius theory incorrect. Nicolaus Copernicus proved Cladius theory incorrect. Nicolaus Copernicus was a Renaissance astronomer, mathematician, physician, array leader, classical scholar, translator, artist, Catholic cleric, jurist, governor,...If you want to get a spacious essay, order it on our website: OrderEssay.net
