Third quarter Moon. The lunar phases arise as the Earth-Moon-Sun angle changes as the Moon orbits the Earth. This waning Moon is 21 days into its 28-day cycle (third quarter). On a waning Moon,the day-night line (terminator) marks the lunar sunset as night advances over the Earth-facing side of the Moon. This image,published in 2011,combines data from the Clementine and Lunar Reconnaissance Orbiter spacecraft. The image is part of a sequence of lunar phases (see images C011/1544-1551),orientated for the northern hemisphere. As well as the phases,the sequence also shows variations in the Moon's position and angle | |
