Why does the Moon change shape every night?
The Moon is Earth’s only natural satellite — a rocky ball that orbits our planet roughly every 27 days. Unlike the Sun, the Moon doesn’t produce its own light; we only see it because it reflects sunlight.
As the Moon orbits Earth, different amounts of its sunlit side face us — creating what we call “phases.” The Moon isn’t actually changing shape at all; we’re just seeing different portions of it lit up.
