Full Moon

Full moon is a lunar phase that occurs when the geocentric apparent longitudes of the Sun and Moon differ by 180 degrees; the Moon is then in opposition with the Sun. At this time, as seen by viewers on Earth, the hemisphere of the Moon that is facing the earth (the near side) is fully illuminated by the Sun and appears round. Only during a full moon is the opposite hemisphere of the Moon, which is not visible from Earth (the far side), completely unilluminated. As a lunar month is about 29.531, the period between full moons can be either 29 or 30 days.
