With the development of the heliocentric model by Nicolaus Copernicus in the 16th century, the sun was believed to be the center of the Universe, with the planets (including Earth) and stars orbiting it.
The first development of a heliocentric theory came from Aristarchus of Samos around 270 BCE. Aristarchus calculated the size of the earth and the distance to the Sun and determined that the Sun was much larger than the earth.
