This 4K visualization shows the moon's phase and libration at hourly intervals throughout 2017, as viewed from the Southern Hemisphere. Each frame represents one hour. In addition, this visualization shows the moon's orbit position, sub-Earth and subsolar points, distance from the Earth at true scale, and labels of craters near the terminator.
