Copernicus was born in Poland on February 19, 1473 and died on May 24, 1543, at 70 years old, in Prussia. He is considered the father of the heliocentric theory. That is, that the all stars rotate around the sun. In the terrestrial case, Copernicus formulated the astronomical theory in which he explained that the planets revolved around the sun and against the geocentric belief that he believed that all the planets revolved around the Earth, center of creation of the universe, according to the Catholic Church during the Renaissance.
Copernicus refrained from publishing his work until his death, despite having the ecclesiastical support, and who was also a Catholic priest. However, after his death, his works were included in the "Index librorum prohibitorum" or "Index of Forbidden Books" by the Catholic Church, which excommunicated all who read these works.
