2. WHAT DID HE BELIEVE?
Johannes Kepler firmly believed in
the Copernican system. Meaning :the
reason that the orbit of Mars was
particularly difficult was because
Copernicus had correctly placed the Sun
at the centre of the Solar System, but had
incorrectly assumed that the orbits of
planets were in circles.
3. WHAT HAPPENED NEXT?
Kepler was forced to realize that the
orbits of planets were not the circles as
dubbed by Aristotle and assumed theory
by Copernicus, but were instead they
were "flattened circles" called ellipses.
This information would allow Kepler to
eventually form his correct theory of the
Solar System and later eliminate Brahe's
theory!
