Here’s how you can categorize each of the items:

Aristotle:

  • Geocentric
  • Planets fixed on nested spheres

Ptolemy:

  • Planets fixed on epicycles
  • Accurately predicted the positions of the planets

Both (or could be related to both):

  • Geocentric (this concept is often associated with Aristotle but was also part of Ptolemy's model)

So the final categorization is:

  • Planets fixed on nested spheres – Aristotle
  • Geocentric – Aristotle (Also related to Ptolemy)
  • Planets fixed on epicycles – Ptolemy
  • Accurately predicted the positions of the planets – Ptolemy
