Lunar Librations
Relative to an observer on Earth, the moon appears to wobble.
This wobble is caused by parallax artifacts due to the rotation of the Earth,
the elliptical orbit of the moon, and the fact that the moon's orbit
is inclined at about 6° to the ecliptic.
Consequently, about 59% of the moon's surface can be observed from Earth (but not all at once!).
Mare Crisium is visible in both images, but Mare Fecunditatis
has rotated across the terminator in the right-hand image.
