New is when the moon is in front of the earth and full is when it is behind the earth because the sun is shining directly onto it, face on.
answer is syzygy
The answer is syzygy.
conjunction (new) opposition (full)
Full Moon.
a full moon.

full moon
The phase of the moon depends on it position in relation to the earth and the sun. For instance, when the moon is in between the earth and the sun, this is the new of full moon phase.
We're going to assume that the question is referring to the next Full Moon.The moon makes one complete orbit each 27.32 days, but the phases repeat witha period of 29.53 days. So the elapsed time from any phase to the next appearanceof the same phase is (29.53/27.32) = 1.081 orbits.
The position of the earth and moon on their orbit around the sun, determines how much and what area of the moon is lit by sunlight. The moon's phases are what we can view from the earth.
There are diagrams of the Moon position (for each phase) at the related links.
Because the Moon's orbit around the Earth is not in the plane of the Earth's orbit around the Sun. The Moon's orbit is tilted at approximately 5 degrees to the Earth's orbit around Sun. As the Moon orbits the Earth, it is usually either "above" or "below" the Earth's orbital plane around the Sun. Greg
It takes the moon 29.5 days to go through all phases, from full moon, back to full moon for example. Relative to the background stars and ignoring the earth position relative to our sun, the moon takes 27 days 7 hours and 43 minutes to orbit the earth - the sidereal orbit. During this time, the earth has progressed around the sun a little, on its orbit around the sun. For the moon to get back to exactly the right phase, it takes a little longer, 29 days, 12 hours and 44 minutes in total from full moon to the next full moon.
