Key features on the visible face of the Moon.
The single large moon of the planet Earth. A cratered and barren body, its orbit is such that, within
certain minor variations, it always shows the same face towards its mother planet.
The first sliver of a New Moon, when the Moon begins to move away from the
Sun in the sky, appears at intervals of about 29½ days. This regular event forms the basis of some of
Earth's oldest calendars.
