Question

Suppose you see a moon that is half bright and half dark in your early evening sky. Then you are seeing a __________ moon.

Answer 1

A moon that is half bright and half dark in the early evening sky is a waning gibbous moon.

Step-by-step explanation:

When you see a moon that is half bright and half dark in your early evening sky, you are seeing a waning gibbous moon. This occurs after the full phase, when the illuminated portion of the Moon starts to decrease. In a waning gibbous moon, more than half of the Moon's illuminated hemisphere is visible, but less than during the full phase.

Answer 2

Sounds like you're seeing the moon exactly half illuminated, AND it's been roughly a week since a New Moon.

Then you're seeing the First Quarter moon.
