Eudoxus believed that the Earth was the center of the universe, with the stars, planets, and the Sun orbiting around it in perfect circular motion. This geocentric model was later refined and expanded upon by other ancient Greek astronomers.
The Greek astronomer Claudius Ptolemy believed that Earth was at the center of the universe in his geocentric model, which was widely accepted in the ancient world. This view held sway until the heliocentric model proposed by Copernicus in the 16th century challenged it.

No--he believed that the sun was the center of the universe.
The geocentric model, where Earth is the center of the universe and planets have circular orbits, was proposed by ancient Greek astronomer Ptolemy in the 2nd century. This model was accepted for over a thousand years until Copernicus introduced the heliocentric model in the 16th century.
