Who created the model of the solar system in which all the plants orbited the sun?

Answer 1

The idea that the Earth revolves around the Sun had been proposed in the 3rd century BC by Aristarchus of Samos.

In the 16th Century this idea was revived and a fully poredictive heliocentric model was put forward by Nicolaus Copernicus. This model was subsequently extended by Johannes Kepler.

William Herschel subsequently expanded this model further to show that the Sun was not the centre of the Universe.

Answer 2

The model of the solar system where all planets orbit the Sun was created by Nicolaus Copernicus in the 16th century. This model, known as the heliocentric model, replaced the earlier geocentric model where it was believed that Earth was at the center of the universe.

Answer 3

Nicolaus Copernicus came up with the heliocentric theory. He didn't just wake up one day and say: "I know, let's have the Sun at the centre", but he also did a lot of work producing a system of large and small circles that the planets follow, to make his model agree with observations as closely as possible.

His model was at least as complex as the earlier Earth-centred theory, but a long time later, after Newton's theory of gravity and laws of motion were produced, it became clear that having the Sun at the centre fits theory the best because it is so massive there are no forces in the Solar System which can move it very far.

Answer 4

The essentials of the current model were proposed by Johannes Kepler in the early 1600s. The planets were given planar elliptical orbits with the Sun at (or near) the centre, each inclined slightly to the ecliptic and obeying Conservation of Angular Momentum. After Kepler's time further discoveries explained the dynamic mechanisms involved in maintaining these orbits.

Answer 5

Nicolas Copernicus

He published it at the end of his life to increase the chances of it being accepted.

Answer 6

Ptolemy created that system.
