Moon phases depend on the position of both the Sun and Moon with respect to the Earth. The 4 primary phases of the Moon are: new, first quarter, full and third quarter.
First Quarter Moon. The first quarter moon (often called a âhalf moonâ), happens when the moon is at a 90 degree angle with respect to the Earth and Sun. So we are seeing exactly half of the moon illuminated and half in shadow. Each lunar cycle begins with a new moon.
