Basically he constructed an early model of a strawman against geocentrism resorting mainly to insults. In 1600, Kepler set to work on the orbit of Mars, the second most eccentric of the six planets known at that time. The very small difference from the annual period accounted Tycho concluded there were no such spheres, raising the question of what kept a planet in orbit.[8]. In Copernican astronomy one now had to assume that the orbit J J O'Connor and E F Robertson.

Galileo set to work, completing his Dialogue Concerning the Two Chief World Systems in 1629, which featured three characters engaged in a critical discussion of the cosmological, astronomical, physical, and philosophical aspects of Copernicanism but avoiding the biblical or theological ones. Much has been said on what Kant meant by referring to his philosophy as "proceeding precisely on the lines of Copernicus' primary hypothesis".
