He put the sun at the centre of the solar system,not the Earth as favoured by religion.

To assume that Earth and the other planets move around the sun
Other people recorded their observations of the stars and planets with astrolabes. Ptolemy came up with a (very complicated) mathematical system that would predict the location of planets over time. His basic, geocentric idea was modified over the centuries, but only became more complicated as observations became more exact. Copernicus took these observations that others had written down, and proposed a heliocentric system that he (correctly) noted was far simpler in making accurate predictions.
His most important work, On the Revolution of Heavenly Spheres , was written entirely by him. He used other's astronomical observations, but wrote the book on his own.A fellow mathematician, Georg Rheticus, was very helpful in convincing Copernicus to publish his work.
The discovery did not support Copernicus's theory directly but it raised doubts about the ancient theory of Ptolemy that said that all objects in the sky are in orbit round the Earth. Galileo was an aggressive supporter of Copernicus's theory but eventually it was Kepler's theory that became accepted and is still used today. Both Copernicus and Kepler placed the Sun at the centre but Kepler's elliptical orbits are supported by the later theory of dynamics.

NIcolus Copernicus did many observations on the spica but no one knows who discoveed the Spica Star
Galileo Galilei . He only helped support the theory through his observations , he didn't invent the model, Copernicus did.
his hypothesis was based on informatin gathered from moire recent observations
To assume that Earth and the other planets move around the sun
Shortly before Copernicus died he figured that the Earth was notthecenter of things, but the Sun was. This theory is still used today. He worked out this this theory from detailed observations of the orbit of Mars.

I am not sure they used similes. Copernicus postulated a sun-centered solar system through what today we would call reason and thought experiments. Galileo's careful observations through his telescope confirmed Copernicus's hypothesis.
Copernicus (16C); supported later by Galileo using observations aided by the newly-developed telescope.
Copernicus proposed an idea that was never believed at his time . Aristotle and the Church had taught other people about the geocentric theory, but using observations and math, his heliocentric theory shows that the planets orbit the sun and not the earth.
