Copernicus proposed the idea that the Earth travels around the Sun.
Copernicus felt that Ptolemy's theory was incorrect. Sometime between 1507 and 1515, he first circulated the principles of his heliocentric or Sun-centered astronomy.
Over a 20 year period of time, Tycho Brahe made consistent observations which supported the heliocentric theory proposed earlier by Copernicus. These observations were made using only a compass and a sextant.
In Copernicus' time most astronomers believed the theory the Greek astronomer Ptolomy had developed more than 1,000 years earlier. Ptolomy said the Earth was the center of the universe and was motionless. He believed all other heavenly bodies moved in complicated patterns around the Earth.
