Moon Phase
A measurement of the angle between the Sun and Moon, which determines how much of the Moon's lit half is visible from Earth.
A Moon phase is a direct geometric fact: it's determined by the angle between the Sun and Moon as seen from Earth. When the Moon sits near the same direction as the Sun, its lit side faces away from us (New Moon). As it moves further from the Sun, more of its sunlit half becomes visible, building to a Full Moon when the two are on opposite sides of the sky.
The full cycle -- new to full and back to new -- takes about 29.5 days. The Transits page shows both today's phase name and its exact illumination percentage.
