Aristotle believed the Geocentric was the correct solar system

Aristotle claimed that the earth was the center of the solar system and all the plants were perfect spheres and moved in perfect circles around the earth. The stars were also set, did not move

Aristotle's solar system was flawed. It had made three big flaws, it did not explain why sometimes the planets looked brighter, why the planets looked bigger, and the last one was why the plants sometimes appeared to move backwords. ]]> 2022-01-28 18:39:03 UTC https://padlet.com/dstegnitz0001/Bookmarks/wish/2018462365 dstegnitz0001 https://padlet.com/dstegnitz0001/Bookmarks/wish/2018536710 100 AD - 170 AD

Ptolemy believed in the Geometric solar system

Ptolemy's main improvement focused on explaining Aristotle's three main flaws. Ptolemy added circles called Epicycles that explained why sometimes the planets look different because on top of moving in circles around the plant there doing circles in the circle sounds confusing well ya it is.

The main flaw with Ptolemy's solar system is that it's too messy he had to keep on adding circles to circles and the math just did not mess up, it's too messy.

Copernican believed the heliocentric solar system 

Copernican made a new claim about the solar system he believed the sun was the center of the universe and the correct order of the planets was Mercury, Venus, Earth, Mars, Jupiter, Saturn, and that all orbited the sun and the moon orbited the earth. He also used epicycles but all the epicycles moved at the same speed. Overall he really simplified Ptolemy

Copernican was on the right track but still was far off. The sun was not the center of the universe but the center of the solar system and the planets did not all epicycles at the same speed.

Kepler was a supporter of the heliocentric solar system

Kepler was the first to point out that the orbits did not have to be circler and instead moons planets and the sun moved in ellipses. This idea fit a lot better in the heliocentric modle.  ]]> 2022-02-01 05:31:30 UTC https://padlet.com/dstegnitz0001/Bookmarks/wish/2022684222 dstegnitz0001 https://padlet.com/dstegnitz0001/Bookmarks/wish/2022691486 1564 - 1642

Galilei was a supporter of the heliometric solar system

Galilei telescope put the nail in the coffin for the Geocentric Solar System thanks to Jupiter and Venus. When Galilei saw Jupiters four big moons this proved that not everything orbited the earth. With Venus, he noticed it went through phases like the moon making it look bigger at times which made no sense if it was a Geocentric Solar System. 

With all these people one big flaw they all had was that not the sun nor the earth were the center of the universe but the sun was the center of the solar system.]]> 2022-02-01 05:41:27 UTC https://padlet.com/dstegnitz0001/Bookmarks/wish/2022691486 dstegnitz0001 https://padlet.com/dstegnitz0001/Bookmarks/wish/2022746379 1643 - 2022

We follow nowadays something like the heliocentric solar system but still way different

Now we know the sun is not the center of the universe but its the center of our solar system and the earth and sun orbit the same point which is the Barycenter of the solar system. For sure we now know that the Geocentric solar system is 100% wrong.

Aryabhata believed in the Geometric solar system

Aryabhata made the correctly predicted that the shadows that sometimes appeared on earth were the sun's reflection off the moon and the axis of earth and part of pi and its effect on the moonlight.

Aryabhata helped prove the earth was round to its axis and by pi, he kinda predicted the total size of the earth he was still off by how many units the earth is.

He believed in the Geometric solar system

Aryabhata correctly predicted that the eclipses he saw were the sun being blocked by the moon and that the reason it would only happen sometimes was that the earth was on an axis.
