Tycho Brahe
Tycho Brahe.
In the Tychonic system, proposed by the Danish astronomer Tycho Brahe, the bodies that orbited Earth were the Sun and the Moon.12
While Brahe retained the geocentric concept of a stationary Earth at the center of the universe, he departed from the Ptolemaic system by positing that all other planets revolved around the Sun. Additionally, in his model, an outer sphere containing the fixed stars was considered to revolve daily around the Earth.12
