Which consequence occurred when early astronomers miscalculated the movement of celestial objects in epicycles?

💡 Explanation

Astronomers used `deferent and epicycle` constructions to represent planet motion. These were initially geometrically motivated, therefore an error in their calculation yielded inaccurate projections of the planetary positions from the observer, rather than improving sundial timekeeping.
