The three correct answers that describe Aristotle's model of the solar system are:
- Earth is at the center.
- Each planet spins on an epicycle.
- The stars are attached to the outermost sphere.
Aristotle's geocentric model placed Earth at the center of the universe, with celestial bodies (including planets and stars) moving in circular orbits (epicycles) around it, and the stars being fixed to a sphere that encompassed everything else.
