Here’s how the items are classified according to Aristotle's and Ptolemy's models of the solar system:
Aristotle's Model:
- geocentric
- planets fixed on nested spheres
Ptolemy's Model:
- geocentric
- planets fixed on epicycles
- accurately predicted positions of the planets
Both:
- geocentric
You would place:
- "geocentric" in both Aristotle's Model and Ptolemy's Model
- "planets fixed on nested spheres" in Aristotle's Model
- "planets fixed on epicycles" in Ptolemy's Model
- "accurately predicted positions of the planets" in Ptolemy's Model
