When Ptolemy was alive, people did not know about Uranus and Neptune, as they had not yet been discovered.
Newton's Universal Gravitation and anomalies in Uranus' orbit. J.C. Adams and U.J.J. Le Verrier noticed anomalies in Uranus' orbit and attributed those to another unseen planet pulling on it. That hypothesis isn't possible without the acceptance of Universal Gravitation.

Ptolemy's theory accounted mathematically for the movement of the planets, Sun and Moonand the stars.However, Ptolemy thought the Earth is the center of the universe, which is wrong. Galileo helped prove that the Sun is the center of our solar system by the use of his homemade telescope. Ptolemy thought that the Sun, planets, and stars rested on crystal spheres that revolved around Earth. Ptolemy had toput in things called "epicycles" and other ideas, to make his system work.

Use a teleporter and BAM you're there
Neptune. Because of the accidental discovery of Uranus, it was calculated that a larger body had to have been disrupting it's orbit. A comet, asteroid and star were ruled out as the cause of a disruption because they were incapable of staying in such a regular motion around the sun. Therefore the body had to be a planet. Using the obervational information from Uranus' disruptions it was calculated where Neptune should be at any one time.
Ptolemy never saw a telescope. The first telescopes were invented about 1500 years after Ptolemy died.

No,Jupiter is not the only gas planet, Saturn is a gas planet aswell.

Last year, scientist found a planet the called it Uranus.
he used a telescope to discover Neptune
Replace the letters in this problem with numbers. A letter is the same number every time it appears. I lined up each line but when I post it, it alters it a little. It should look like a 4-line addition problem (MARS + VENUS + SATURN + URANUS, all of which total "NEPTUNE"). Line them up like you would normally when adding four different number sets. (you will use all #'s 0-9) MARS VENUS SATURN + URANUS ------ NEPTUNE
how they use to do it
