← HistoryWhich outcome occurs when a medieval astrolabe suffers parallax error?
A)Declination misaligns stars' angular height✓
B)Ecliptic plate detaches via oxidation
C)Hour lines shrink from thermal stress
D)Limb fractures during transport cycles
💡 Explanation
Parallax error during sighting celestial objects with an astrolabe introduces angular displacement due to viewing angle differences affecting declination, because the alidade aims from surface level. Therefore, declination misaligns, rather than physical fractures or thermal issues which are separate failure modes.
