Why Does the Moon Seem to Change Shape?
The Moon doesn’t actually change shape, it only appears to.
The Sun always lights up half of the Moon. As the Moon orbits Earth, we see different portions of that sunlit half.
This changing view creates the Moon’s phases over a 29.5-day lunar month.
When the Sun fully illuminates the side facing Earth, we see a Full Moon.
When most of the lit side faces away from us, we see a New Moon.
In between, we see crescents and quarter phases as the visible light grows (waxing) and then shrinks (waning).
Because the Moon rotates at the same rate it orbits Earth (called tidal locking), we always see the same side, just lit from different angles throughout the month.
