How did Nicolaus Copernicus come up with the heliocentric theory?

In 1514, Copernicus distributed a handwritten book to his friends that set out his view of the universe. In it, he proposed that the center of the universe was not Earth, but that the sun lay near it. In it, Copernicus established that the planets orbited the sun rather than the Earth.

When did Copernicus discover the heliocentric theory?

Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.
