Which phase describes a lunar body that is more than half illuminated but not fully?

• A. Half phase
• B. Gibbous phase
• C. Crescent phase
• D. Quarter phase

Answer: (B)

The gibbous phase describes a lunar body that is more than half illuminated but not fully illuminated. This phase occurs when the moon is in the later stages of its waxing cycle leading up to a full moon or in the earlier stages of its waning cycle after a full moon. During this time, the visible illuminated portion of the moon appears bulging or swollen, which is the characteristic of a gibbous phase. The other phases such as half phase, crescent phase, and quarter phase either indicate a lesser amount of illumination (like the crescent which shows a thin sliver or quarter phase representing half illumination) or do not fit the description of being more than half illuminated, hence distinguishing the gibbous phase as the most appropriate answer in this context.
