← HistoryWhich outcome occurs as the equant point shifted in Ptolemaic astronomical models?
A)Planetary albedo values increased
B)Observed planetary motions vary✓
C)Star parallax amplitudes reduced
D)Lunar orbital periods stabilized
💡 Explanation
Observed planetary motions appeared non-uniform because the *eccentricity* relative to Earth shifted. This increased complexity, rather than eliminating it, to improve accuracy with observations; therefore the visible speed changes, not lunar changes.
