What was Copernicus theory about the planets?
Nicolaus Copernicus was an astronomer who proposed a heliocentric system, that the planets orbit around the Sun; that Earth is a planet which, besides orbiting the Sun annually, also turns once daily on its own axis; and that very slow changes in the direction of this axis account for the precession of the equinoxes.

This sentiment had already been expressed in a remark attributed to Alfonso X (1221-1284), the King of Castille and Leon.
