Johannes Kepler did. In perhaps the greatest demonstration of empirical discovery,

he took Tycho's data ... compiled over a lifetime of observing and reporting where

the planets appeared in the night sky ... and deduced three simple statements that

described a system of planetary motion that could produce those appearances.

Kepler didn't say why the planets should behave that way and, technically, he didn't

even say that they do behave that way. He merely said: Here's a system to describe

the motion of the planets, and by the way, it fits what we actually see the planets

doing in the sky over periods of many years, and it's simpler than any other system

that's ever been offered, so there may be a good chance that it's true.

Almost 100 years later, Isaac Newton was writing his own hypotheses, theories,

and conjectures, including his 'laws' of motion and his 'law' of gravity. He was able

to show that IF his laws of motion and gravity are correct, then one result would be

that moons and planets MUST behave according to Kepler's laws.

Was Copernicus on house arrest?

No, Copernicus was not on house arrest. He was a Renaissance mathematician and astronomer who proposed a heliocentric model of the universe in which the Earth and other planets revolve around the Sun. His work was published and widely discussed during his lifetime.


Who proved the accuracy of Copernicus ideas about motion of planets?

Johannes Kepler was the one who provided the evidence and mathematical framework to support Copernicus' heliocentric model of the solar system through his laws of planetary motion.


The polish astronomer lived from 1473-1543?

The Polish astronomer you are referring to is Nicolaus Copernicus. He is known for proposing the heliocentric model of the solar system, where the sun is at the center and the planets revolve around it. Copernicus's work laid the foundation for modern astronomy and revolutionized our understanding of the universe.


Who first said that the planets revolved around the sun was?

It was nicoholas capernicum ___________________________ The earliest known person to write that the Earth moved around the Sun was the Greek astronomer and mathematician, Aristarchus of Samos.


How was Copernicus' model of the universe different from Ptolemy's model?

The main difference was that Ptolemy's model was geocentric (Earth-centred) and Copernicus's was heliocentric (Sun-centred). Ptolemy's model came from ancient times while Copernicus's was much later (1543). Both models represented the planets' orbits by using combinations of circles and epicycles to explain the way the planets move among the stars. Copernicus found that the orbits of the inner planets could be explained more simply. That is to say that the epicycles used for all the orbits were smaller, and for the inner planets a lot smaller. Both models represented the planets' positions with reasonable accuracy given the crude observational methods used in those days. Until gravity and the laws of dynamics were discovered about 150 years after the publication of Copernicus's system, there was no way of deciding which model was the 'right' one.

Who predict that the planets circle around the sun?

Nicolaus Copernicus, a Polish mathematician and astronomer, proposed the heliocentric model in the 16th century, stating that the planets, including Earth, orbit around the Sun. This model replaced the geocentric model that had Earth at the center of the universe.

What scientist created the copernican heliocentrism?

Nicolaus Copernicus, a Polish mathematician and astronomer, is credited with proposing the heliocentric model of the solar system in his work "De revolutionibus orbium coelestium" published in 1543. This model placed the Sun at the center of the solar system with the planets, including Earth, revolving around it.
