Tycho Brahe (1546-1601)

Tycho Brahe
A Danish astronomer, lived before the telescope was invented and made the most accurate observations with the naked eye ever known.
Like most astronomers of the time, he was employed by his king as an astrologer who had to cast horoscopes,
but his real interest was the movement of the planets.
He believed that the planets orbit the sun , but he also thought that the sun orbits the earth,
and that our planet was the center of the universe.
Brahe set out to prove this by observing the positions of the planet
After His death the observations reached the hands of Johannes Kepler, who was studying the same problem.
Brahe's naked-eye observations helped Kepler prove that the earth also revolves around the sun,
and that the planets move in ellipses, not circles.
