Question

keplers first and third laws quick check
which orbital shape did most scientists in the early 1600s think the planets of our solar system have? (1 point)
○ circular
○ parabolic
○ elliptical
○ hyperbolic

Explanation:

In the early 1600s, before Kepler's work showing elliptical orbits, the prevailing view among most scientists was that planetary orbits were circular, influenced by the idea of perfect geometric shapes in the heavens (e.g., from Aristotelian and Ptolemaic models). Parabolic, elliptical (Kepler's discovery came later), and hyperbolic were not the dominant beliefs for planetary orbits at that time.

Answer:

A. circular
