Seasonal variation in the phases of the Moon, illustration. As the Moon orbits the Earth, the amount of sunlight seen on its visible hemisphere varies in a regular cycle of just over 29 days (the synodic month). This montage of images shows the cycle: a new Moon; a waxing crescent Moon; the Moon's first quarter; a waxing gibbous Moon; a Full Moon; a waning gibbous Moon; the Moon's third quarter; and a waning crescent Moon. The images shown in the red arrowed circle are the Moon as seen from space in the northern hemisphere's summer. The images in the red boxes show the Moon as seen from the Earth in the northern hemisphere's summer. The blue arrows show part of the equivalent cycle in the northern hemisphere's winter when the Moon is higher in the sky. Distances shown here are not to scale. | |
