Lunar Libration
« on: December 23, 2011, 12:58:20 AM »
Do not know if anyone has ever heard of libration.  This is the phenomenon of a planet's moon oscillating in relation to the planet, even if the moon is tidally locked to the planet.

Animation Showing Luna's Libration


Here is an article at wikipedia on libration.  This article has the same animation as shown above.

Here is a good article on observing the lunar libration zones (pdf).

Just something more a GM has to consider when constructing an alien world.
