What are moon phases?
According to NASA, the moon moves through its phases as it completes a 29.5-day orbit around Earth. The phases we see are caused by the changing angles between the Sun, Moon, and Earth. From Earth, the moon can appear full, partly lit, or seem to disappear entirely, but it’s always the same side facing us. What changes is how much sunlight reflects off its surface, depending on where it is in orbit. This pattern is known as the lunar cycle.
The eight main moon phases are:
New Moon - The moon is between Earth and the sun, so the side we see is dark (in other words, it's invisible to the eye).
Waxing Crescent - A small sliver of light appears on the right side (Northern Hemisphere).
First Quarter - Half of the moon is lit on the right side. It looks like a half-moon.
Waxing Gibbous - More than half is lit up, but it’s not quite full yet.
Full Moon - The whole face of the moon is illuminated and fully visible.
Waning Gibbous - The moon starts losing light on the right side. (Northern Hemisphere)
Third Quarter (or Last Quarter) - Another half-moon, but now the left side is lit.
Waning Crescent - A thin sliver of light remains on the left side before going dark again.
