Question

copernicus and other astronomers before him thought that celestial bodies followed a ______ orbital path.
○ circular
○ square
○ elliptical

Explanation:

In the history of astronomy, Copernicus and earlier astronomers held the view that celestial bodies moved in circular orbits. Kepler later discovered that planetary orbits are elliptical. A square orbital path is not a scientifically recognized or plausible orbital shape for celestial bodies. So the correct option is the one related to circular.

Answer:

A. circular
