Question

which orbital shape did most scientists in the early 1600s think the planets of our solar system have? (1 point)
hyperbolic
circular
elliptical
parabolic

Explanation:

Before Kepler's laws, the dominant view (influenced by ancient Greek thought like that of Ptolemy and Aristotle) was that celestial bodies (including planets) moved in perfect circular orbits. Kepler later showed that they are elliptical. Hyperbolic and parabolic orbits are for objects escaping the Sun's gravitational pull (not for bound - orbit planets in the long - term).

Answer:

circular
