The 9 Moon phases
Wondering what's the moon phase today? The moon rotates around the Earth every 29.5 days. During this time, it forms 8 main phases till the next full moon, and the very brief "Old Moon":
🌑 New moon occurs when the Moon cannot be seen because we are looking at the unlit half of the Moon. The new moon phase occurs when the Moon is directly between the Earth and Sun. A solar eclipse can only happen at new moon.
🌒 Waxing crescent moon occurs when the Moon looks like crescent and the crescent increases ("waxes") in size from one day to the next.
🌓 First quarter moon occurs when half of the lit portion of the Moon is visible after the waxing crescent phase. It occurs approximately a week after new moon.
🌔 Waxing gibbous moon occurs when more than half of the lit portion of the Moon can be seen and the shape increases ("waxes") in size from one day to the next. The waxing gibbous phase occurs between the first quarter and full moon phases.
🌕 Full moon occurs when we can see the entire lit portion of the Moon.
🌖 Waning gibbous moon occurs when more than half of the lit portion of the Moon can be seen and the shape decreases ("wanes") in size from one day to the next. The waning gibbous phase occurs between the full moon and third quarter phases.
🌗 Last quarter moon (or a half moon) occurs when half of the lit portion of the Moon is visible after the waning gibbous phase.
🌘 Waning crescent moon occurs when the Moon looks like the crescent and the crescent decreases ("wanes") in size from one day to the next.
Old moon occurs when a moon with only a tiny bit of it seen in the corner, about to turn into a new moon.

A full moon occurs when the Moon is on the opposite side of the Earth from the sun, and we see it fully illuminated. A Full Moon occurs twelve times a year, and each occurrence has a different name (or several different names) based on culture and folklore. In the Northern Hemisphere, Moon names are specific to the time of year in which they occur. Native Americans primarily assigned names to each of the Full Moons depending on time of the year, weather cycles, hunting, harvest, fishing and/or planting seasons. Other Full Moon names originated in Europe and the names were integrated with Native names, and by 1955 distinct names for Full Moons became listed in The Farmer’s Almanac.
A supermoon is a full moon, or new moon, that occurs near to the perigee—the point in the orbit of the moon which is nearest to the Earth—resulting in a slightly larger-than-usual apparent size of the moon as viewed from Earth.
