🔍 Key Concepts

• Celestial navigation corrections applied to planets and the Moon • Difference between an object's geometric (true) center and what appears through a sextant when it is not fully illuminated • How phase and semidiameter are used when bodies are only partially lit

💭 Think About

• Think about when the center you "see" through the sextant is not the same as the true physical center of the planet—what causes that? • Which of these corrections is specifically associated with a body being partly illuminated, like a crescent or gibbous shape? • Which correction name would you normally associate with using the limb (edge) of the Sun or Moon rather than its center?

✅ Before You Answer

• Identify which correction is linked to partial illumination (crescent, gibbous) of a planet or the Moon • Separate in your mind: atmospheric effect vs. shape/illumination effect • Recall that semidiameter correction is tied to using a limb instead of the center—verify whether that’s what the question is describing
