Clouded moon near sideThe Moon's lighting is amazing!!! like a lips in a kiss. There she is, the woman in the moon. So clearly defined in this picture.

The Moon is in synchronous rotation, meaning that it keeps nearly the same face turned towards the Earth at all times. Early in the Moon's history, its rotation slowed and became locked in this configuration as a result of frictional effects associated with tidal deformations caused by the Earth. Long ago when the Moon spun much faster, its tidal bulge preceded the Earth-Moon line because it couldn't "snap back" its bulges quickly enough to keep its bulges in line with Earth. The rotation swept the bulge beyond the Earth-Moon line. This out-of-line bulge caused a torque, slowing the Moon spin, like a wrench tightening a nut. When the Moon's spin slowed enough to match its orbital rate, then the bulge always faced Earth, the bulge was in line with Earth, and the torque disappeared. That is why the Moon rotates at the same rate as it orbits and we always see the same side of the Moon. Photo taken of the moon's "near side" on 24th December 2007. Using my camera's maximum 18 x optical zoom or 648mm. De maan is, samen met de zon en de draaiing van de aarde, verantwoordelijk voor de getijdenwerking op de aarde. Deze getijdenwerking zorgt ervoor dat de draaisnelheid (rotatie) van de aarde langzaam afneemt. Van haar kant oefent de aarde ook getijdenwerking op de maan uit, maar wel van een orde grootte sterker. Hierdoor is de draaisnelheid van de maan al zo sterk afgenomen dat zij precies evenveel tijd nodig heeft om om haar eigen as te draaien, als éénmaal om de aarde (synchrone rotatie). Dat verklaart waarom we vanaf de aarde altijd dezelfde kant van de maan zien. CommentsAstrid Photography.
