We call this motion “libration in longitude.” When the Moon is farthest from Earth and orbiting at its slowest, its rotation gets a little ahead, and we see a bit more of its western side. When the Moon is at its closest to Earth and moving most quickly along its orbital path, the Moon itself doesn’t rotate quite fast enough to keep entirely the same side facing us, and we get to see a little more of the eastern side of the Moon.

The Moon’s rate of rotation around its own axis, though, always stays the same.

Be the first person to complete all ten phases to win the game. Each deck features “Wild” and Skip” cards, which add excitement and can help you get out of a sticky situation.
