Actually Nicholas Copernicus did, but he was afraid unlike Galileo Galilei and Nicholas published his findings when he was close to death he knew his beliefs would get him in trouble with the Roman Catholic Church. Galileo did make a telescope and discovered Jupiter had moons that went around it and used it as proof. In the end of his life when he was older he was put under house arrest. His assistant was able to trick the guards and smuggle his book to get published.

Which planets move in an elliptical orbit?
All the planets move with an elliptical orbit, but with a very low eccentricity.
Do planets move around the sun circular in orbit?
No, planets do not move around the sun in perfect circles. Instead, they follow elliptical orbits, which are elongated circles. This means that the distance between a planet and the sun varies as it moves along its orbit.
What was Ptomeny trying to explain in his model by having the planets move on smaller circles that move on bigger circles?
to explain the motion of planets, especially the phenomenon of retrograde motion where planets appear to temporarily reverse their direction of motion. Ref: Andrew Liddle "An Introduction to modern Cosmology".
Which planets' motions were described with epicycles in the Ptolemaic system?
In the Ptolemaic system, the motions of Mercury, Venus, Mars, Jupiter, and Saturn were described with epicycles. These epicycles were small circles that the planets were thought to move in while also orbiting the Earth on larger deferent circles.
How Do Planets Travel Around The Sun?
Planets travel around the Sun in elliptical orbits due to the gravitational pull of the Sun. This gravitational force keeps the planets in their respective paths, causing them to move in a continuous loop around the Sun. The speed at which a planet travels around the Sun depends on its distance from the Sun and the mass of the Sun.
What was ptolemys explanation for why the planets seemed to move at different speeds?
The planets move on little circles that move on bigger circles.
He developed the theory that planets move in concentric circles around the earth?
This theory was developed by the ancient Greek astronomer Claudius Ptolemy. Known as the Ptolemaic system, it held that planets move in circular orbits around the Earth. This geocentric model was widely accepted until the heliocentric model proposed by Copernicus in the 16th century.
Who astronomer disproved the idea that planets move in a circular orbit?
kepler
What was Ptolemy trying to explain in his model by haven't the planets move on smaller circles that move big circles?
ptolemy did something
Who belived that the planets move in epicycles?
The Greek astronomer Ptolemy believed that the planets move in epicycles, which are small circles that the planets orbit while also moving along their larger orbital paths. Ptolemy's geocentric model of the universe was widely accepted for centuries until it was eventually replaced by the heliocentric model proposed by Copernicus.
Who was the German astronomer who proved that the planets move in oval paths called ellipses?
Johannes Kepler was the German astronomer who proved that the planets move in oval paths called ellipses. His work laid the foundation for the laws of planetary motion.

What was ptolemy trying to explain in his model by having the planets move move on circles that move on bigger circles?
Ptolemy is trying to explain in his model that each circle represents 1 planet's rotation and it's a scale drawing of the distance apart from each one!
Do planets move in elliptical orbits?
The planets move intheir ellipticalorbits becauseof the gravitation of the Sun combined withthe inertial velocity of the planets(tangentialto their orbital paths). Mathematics shows the resulting orbits must be ellipses. (Some of the ellipses are in factalmost circles.)
