lunar
The moon orbits the Earth
The far side.
That's the "near side".
This is called "The New Moon"
That's the "far side".
The new moon phase occurs when the moon lies between the sun and Earth, with the side facing Earth in shadow. This position causes the moon to be not visible from Earth as the illuminated side faces away.
There are high tides on the side of Earth facing the moon.
The "near" side of the moon is the side that always faces Earth. The "far" side of the moon can only be seen from space. The dark side of the moon is the title of a Pink Floyd album. There is no side of the moon that is always dark.
The Dark side of the moon. Note that this is a slightly poetic name as unless we see a Full Moon, it does receive light from the sun.
The New Moon is when the lit side of the moon is facing away from Earth, and only the dark side is visible.
The Moon is tidally locked to Earth; the Moon's "day" and the Moon's month are the same length. So the "near side" of the Moon always faces the Earth, and the "far side" always faces away from Earth.
The Earth has only one moon so the Earth's moon name is Moon, The Moon or it can be the Latin name "Luna".
