What are 6 early ideas about planetary motion?

Question

i mean 2 early ideas about planetary motions?

Answer 1

I don't know what 6 you mean, but here are a few:
1) the planets orbit the Earth as does the sun (geocentric)
2) the planets exhibit "epicycles" or small circles in parts of their orbits
3) the planets had circular orbits
4) the planets are independent of attraction (gravity) of other planets
