1500s
Nicholas Copernicus 1473-1543 was a Polish priest and astronomer who created an alternative model of the planets which put the Sun at the centre, instead of the Earth as generally accepted at that time.He knew it would get him into trouble with the church, and his book 'De Revolutionibus' was not published until the year he died. The theory with the Sun at the centre was similar to the old Ptolemaic system with its collection of circles and epicycles allowing for the changes in distance and the changes in planets' speeds, and their departure from the ecliptic.In the late 1500s Tycho Brahe made new more accurate observations of the planets from Denmark, and these were used by Johannes Kepler to produce a new model published in 1609.Kepler's model is the one we use today, and it has the Sun at the centre, like the Copernican model, but all the other details of Copernicus's theory were rejected in favour of elliptical orbits.
Aristrachus of SamosThe first man to theorize that the Earth revolved around the sun is believed to be Nicolas Copernicus. In the 1500s he speculated that rather than the sun circling the Earth, the Earth may actually orbit the sun.

It was Copernicus.
I am not sure which of his books you are asking us about, since he wrote at least three of them. But his best known was On the Revolutions of the Celestial Spheres (in Latin,De revolutionibus orbium coelestium). Nicolaus Copernicus was an astronomer, and this book taught something entirely new for the 1500s-- that the planets revolved around the sun.

1500s
The first astronomer to dispute the model seriously was Nicholas Copernicus in the 1500s. His model used circles and epicycles, like the old Ptolemaic model, but had the Sun at the centre, which led to its being named the heliocentric model. Sixty years after his death in 1543, the Copernicus model was taken up by Galielo in his dispute with the Catholic church. In the latter half of the 1600s further discoveries led to wider acceptance of the heliocentric concept. However the rest of the Copernicus model was discarded and replaced by Kepler's model which had each planet in an elliptical orbit, and this was taken up and given scientific credibility by the discoveries of Newton and others.
His views went against traditional beliefs, including those of the Roman Catholic Church.
