Q:

Where does "gibbous moon" mean?

A:

The term "gibbous moon" refers to the phase of the moon's cycle when more than half but less than all of the moon is illuminated by the sun, making it visible from Earth. A gibbous moon can be either waxing or waning, explains Universe Today.

The gibbous moon phase occurs twice in each complete lunar cycle. As the moon transitions from a new moon to a full moon, the moon undergoes a waxing gibbous phase prior to becoming a full moon. As the cycle reverses, the moon becomes a waning gibbous moon as it transitions from a full moon to a third quarter moon.

  • Q:

    Why does the moon appear bright?

    A:

    The moon appears bright because the side visible on Earth reflects the light from the sun. As the moon and the Earth move around their respective orbits, different portions of the moon are visible to people on Earth, depending on the angle at which the light hits the moon and reflects back to Earth. The moon reflects back about 12 percent of the light from the sun that hits it.
