It is not a term used in astronomy and there is no single accepted definition of it. [2] Among the meanings ascribed to it are these: a second new moon that appears in the same month; the third new moon in an astronomical season ...
The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic longitudes of the Sun and Moon differ by 180°). [3] This means that the lunar hemisphere facing Earth—the near side —is completely sunlit and appears as an ...

A lunar phase or Moon phase is the apparent shape of the Moon 's directly sunlit portion as viewed from the Earth (because the Moon is tidally locked with the Earth, the same hemisphere is always facing the Earth). In common usage, the four major phases are the new moon, the first quarter, the full moon and the last quarter; the four minor ...
