The astronomical system of Ptolemy, in which the earth is at the center of the universe with the sun, moon, planets, and stars revolving about it in circular orbits.
Ptolemaic system Ptolemy believed that Earth was at the center of the universe and that the Sun and planets orbited Earth (with the planets also moving in smaller circles called epicycles). In this system, the centers of Mercury's and Venus's epicycles always lie on the line shown in the diagram between the Earth and the Sun.

He developed the theory that planets move in concentric circles around the earth?
AAristotle developed the theory that planets are spheres and move in concentric circles around the sun
What was Ptolemy's theory?
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.
How are Copernicus theory and Ptolemy theory have in common'?
Well copernicus s theory was the heliocentric theory which is that the sun is center and the planets and stars revolve around it ptomely s idea was the geocentric theory which is that the earth is center and other planets and stars revolve around the earth
What was the major error in Ptolemy's theory about the structure of the universe?
Ptolemy's theory was incorrect because he believed the Earth was at the center of the universe and that the other planets and the Sun revolved around it. However, he was later corrected by, I believe, Copernicus (Ca-per-ni-kus) who stated the Sun was in the center of the universe and that the planets, including Earth, revolved around it.
Who belived that the planets move in epicycles?
Ptolemy.

How was Copernicus model of the universe different from ptolemy's?
Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the moon.No. The above answer is incorrect.Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the EARTH in epicycles. Not the moon. (The model that modeled the planets orbiting earth was the Geocentric model. Aristotle theorized this.)Copernicus's model is known as the Heliocentric model. Ptolemy's theory of epicycles is when the planets revolved in large circles around Earth.

Did ptolemy believe in helio?
His theory was geo. The heliocentric theory is modern and has the Sun at the centre of the solar system with the planets going round it in nearly-circular orbits. Ptolemy's theory, a geocentric one, had the Earth at the centre, with everything else orbiting round it, but Ptolemy found an ingenious way of accounting for the planets' movements in the sky quite accurately. Ptolemy's method describes the planets' orbits in terms of a basic circular orbit, called the deferent but what goes round the deferent is a smaller circle, the epicycle, and the planet goes round the epicycle. It isn't difficult to see that this geometrical construction 'takes out' the Earth's movement round the Sun and explains the planets' movements as we see them from the Earth, while allowing the Earth to be fixed at the centre.

Why was Nicolas Coperincus important to science?
Copernicus gave Helios centric theory against Ptolemy's Geo centric theory. Ptolemy considered earth to be the centre and all other planets including Sun go around the earth. But Copernicus denied this and he gave so rightly that Sun is at the centre and all the other planets including earth go around the Sun.
How is Copernicus description of the system of planets different from Ptolemy description?
Ptolemy thought the earth was the center of the solar system (Otherwise known as the Geocentric theory) and Copernicus's idea was that the sun was at the center of the solar system (Heliocentric theroy).
Who belived that the planets move in epicycles?
Ptolemy.
