From Earth we only see one face of the moon. But it’s not always the exact same face. The moon rotates once on its own axis during each 27-day journey around the Earth. But as the moon makes its elliptical orbit, its velocity varies and alters that synchronicity, causing our perspective of the “light side” to appear at slightly different angles throughout any given month. In short, the moon wobbles. Photo: NASA
