Question

Quizplus · Accepted Answer

Tycho Brahe's model of the solar system was geocentric, meaning it placed Earth at the center, with the Sun and other planets orbiting around it. This model did not incorporate elliptical orbits, which were later proposed by Johannes Kepler, nor did it directly involve the complex Ptolemaic system of deferents and epicycles designed to explain retrograde motion. Brahe's model specifically had the Sun orbiting Earth, distinguishing it from the heliocentric models that followed.
