When the moon is located between Earth and the sun, the phase of the moon that is seen is the new moon.
The phase of the moon that is seen when it is located between Earth and the sun is called the "new moon." To understand this, let's think about the positions of the Earth, moon, and sun. During a new moon, the moon is positioned between the Earth and the sun, with the sun's light being blocked from illuminating the side of the moon that faces us on Earth. As a result, the side of the moon that we see appears dark, making it difficult to see any part of the illuminated moon. This phase is referred to as the "new moon."
