← HistoryWhich property arises from the geometric projection within astrolabes?
A)Planisphere distortion effects arise✓
B)Epicycle correction over-estimates parallax
C)Equant point induced acceleration variations
D)Zenith angle dependent error gradients
💡 Explanation
The astrolabe projects the celestial sphere onto a flat plane, so planisphere distortion necessarily appears because a sphere can't be perfectly mapped onto a disk without some areas being enlarged while others shrink. Therefore distortion is the result, rather than perfect fidelity.
