Who said that the sun revolved around earth in nicolaus Copernicus time?

Answer 1

In 1530, Copernicus completed and gave to the world his great work De Revolutionibus, which asserted that the earth rotated on its axis once daily and traveled around the sun once yearly: a fantastic concept for the times.

Answer 2

He published the theory of the planets' orbits in his book "De Revolutionibus" in the year he died, which was 1543. Part of the theory was that the Sun was at the centre and all the planets revolve around it.

Copernicus's theory resembled the Ptolemaic theory in having circles and epicycles to explain the paths of the planets. He found that by putting the Sun at the centres the orbits were geometrically simpler than in the Ptolemaic theory, because the inner planets did not need large epicycles, which were present in the Ptolemaic theory to (as we now know) take out the Earth's movements.

When Kepler produced his heliocentric theory in 1609 he threw out the circles and epicycles of the old theories and instead he had the planets moving in elliptical orbits. This was the theory that eventually gained acceptance after the elliptical orbits were explained by Newton in terms of the theories of gravity and motion.

Answer 3

Well, um, the sun isn't in the center of the earth. I believe you're asking when he discovered that the earth orbited the sun.

The answer to that would be that he published his studies in 1543 (after his death). One might assume that he formed his theory before then.

Answer 4

Copernicus never claimed that the Sun is at the center of the earth.

Until Copernicus, it was believed that the ancient Greek philosopher, Ptolemy was correct: that the Earth was at the center of the Universe.

In 1512, Copernicus published his first paper that claimed that it was really the Sun that was the center, but of the Solar system, not the universe.

Answer 5

During Copernicus's time, the prevailing belief was that the sun revolved around the Earth. This geocentric model was supported by the teachings of the ancient Greek astronomer Ptolemy.
