What are the Moon phases?
The Moon is a spherical object, and it's consistently half-illuminated by the Sun in space. Yet, as the Moon travels around the Earth, its appearance in our sky is constantly changing. The different Moon phases show us how much of the Moon's illuminated side we can see from the Earth’s perspective at a given time.
All the Moon phases in order
There are eight traditionally recognized Moon phases. The four major phases are the Full Moon, New Moon, First Quarter, and Last Quarter. In between, there are four minor ones: the Waxing Crescent, Waxing Gibbous, Waning Gibbous, and Waning Crescent. The major Moon phases mark specific moments, while the minor phases span about 7.4 days, with the lunar appearance changing gradually throughout this period.
New Moon
During the New Moon phase, the Moon is positioned between the Earth and the Sun and rises together with the Sun. The Moon's side facing the Earth is not illuminated, so it is dark and cannot be observed. When the New Moon aligns precisely with the Sun and Earth, a solar eclipse occurs.
Waxing Crescent
After the New Moon, a small portion of the lunar disc becomes visible, forming a crescent shape. This phase marks the beginning of the Moon's waxing (growing) period. The illuminated portion of the Moon increases each night.
First Quarter
The First Quarter phase is reached when the Moon has completed one quarter of its orbit around the Earth. During this phase, half of the lunar disc is lit up; that’s why it is also known as the Half Moon. At this point, the Moon is positioned 90 degrees away from the Sun in the sky.
Waxing Gibbous
Following the First Quarter, more than half of the lunar disc receives sunlight, but it’s not fully illuminated yet. The illuminated portion continues to grow, making the Moon appear larger night after night.
Full Moon
The Full Moon occurs when the Earth is positioned between the Moon and the Sun, and the entire lunar disc is illuminated by the Sun. When the Full Moon aligns precisely with the Sun and Earth, a lunar eclipse occurs. The Full Moon rises right after sunset and is visible throughout the night. It is the opposite of the New Moon and is the brightest and most noticeable phase. Learn more about the Full Moons and their traditional monthly names in our Full Moon calendar.
Waning Gibbous
After the Full Moon, the illuminated portion of the lunar disc begins to decrease. In the Waning Gibbous phase, more than half of the Moon is still visible, but it gradually gets smaller each night.
Last Quarter
Similar to the First Quarter, half of the lunar disc is visible from Earth during the Last Quarter (or the Third Quarter) phase. However, during this phase, the other half of the Moon is illuminated. The Moon is positioned 90 degrees away from the Sun in the sky.
Waning Crescent
The final phase, the Waning Crescent, occurs just before the New Moon. In this phase, only a tiny crescent-shaped portion of the Moon is visible, and it continues to shrink until it becomes the New Moon once again.
What is the Moon cycle?
The Moon cycle is one revolution of the Moon in its orbit around the Earth. During the Moon cycle, we see different phases of the Moon, and they repeat as the Moon repeats its orbit around the Earth. It takes about 29.5 days for the Moon to complete its orbit.
The lunar cycle from New Moon to New Moon is also called a synodic month or lunation.
Moon age
The term "Moon age" typically refers to the number of days that have passed since the last New Moon. It is a way to describe where the Moon is in its lunar cycle.
For example, on the day of the New Moon, the Moon's age is 0 days because it's just beginning its cycle. Since the lunar cycle from New Moon to New Moon lasts 29.5 days, the 29-day-old Moon is the Moon one day before the New Moon.
When will the Moon be visible tonight?
The free astronomy app Sky Tonight can help you find the exact moonrise and moonset times for your location, the Moon’s position in the sky, and more. Scroll through the "Moon" tab in the app's calendar, find the Moon with the search to learn more about it, or find our natural satellite on the sky map and use the time machine to learn where it is located at any given time.
What is the best time to see the Moon?
Here are some tips for you to get the most out of observing the Moon:
The Full Moon is the most exciting phase to observe with the naked eye. It's bright and large and can sometimes appear in unusual colors. However, the Full Moon is not the best phase for close observations because the sunlight falls directly on our natural satellite, leaving no shadows and contrast. Also, the Moon’s light washes out most celestial objects, making stargazing more difficult.
The Waning and Waxing Crescent phases are the best times to observe the lunar landscape through a telescope because the long shadows and pronounced terminator line reveal surface details such as craters and mountains. The Moon appears in a three-dimensional perspective.
Around the First Quarter phase, the Moon is well-seen in the evening hours. This makes it a convenient phase for observations.
Around the Last Quarter phase, the Moon can be observed in the morning. At this time, the shadows on the Moon are at their longest, and the Earth's atmosphere is at its clearest, allowing the finer details of the lunar surface to be observed.
The New Moon phase is perfect for stargazing because when the Moon's disc vanishes, the night sky becomes notably darker. This darkness makes it possible to observe faint celestial objects that can be difficult to see in a moonlit sky.
Overall, each lunar phase has unique traits. Explore each phase and create your own experience!
Which Moon phase is best for stargazing?
While the best phases for viewing the Moon are the First Quarter and Last Quarter, the best lunar phase for night sky observations is the New Moon. During the New Moon, our natural satellite appears as a darkened disc in the sky, invisible to the naked eye; it also rises and sets with the Sun. So the sky is dark and free of moonlight all night.
Don't be upset if you didn't get a chance for observations during the New Moon — during the crescent phase, the sky is also dark enough. Besides, you can choose the time when the Moon is under the horizon or observe the part of the sky far from the Moon. The same tip applies to observations during the First Quarter or Last Quarter Moon, when the lunar disk appears half-lit.
As the lunar phase changes, so does the brightness of our natural satellite (but not in the way you might think). The Full Moon is six times brighter than a half-illuminated Moon. Interestingly, even three nights before a Full Moon, the lunar disc is only half as bright as during a Full Moon.
P.S. Here is a tip for observing the night sky during a Full Moon — simply hide this bright light source behind something (like a tree) so that its light does not shine directly on your surroundings. Do you know any other observation hacks? Take our quiz to test your skills!
F.A.Q.
How many Moon phases are there?
There are four major lunar phases (Full Moon, New Moon, First Quarter, and Last Quarter) and four minor phases in between (Waxing Crescent, Waxing Gibbous, Waning Gibbous, and Waning Crescent).
Why do we see different phases of the Moon?
We see different phases of the Moon because of its changing position relative to the Earth and the Sun. The Moon doesn't emit its own light; it reflects sunlight. As it orbits the Earth, the angle between the Earth, the Moon, and the Sun changes, and we see more or less of the Moon's lit-up side.
Why do we only see one side of the Moon?
We always see one side of the Moon because the Moon rotates exactly once on its axis each time it completes one orbit around the Earth – a phenomenon known as "tidal locking" or "synchronous rotation." By the way, the far side of the Moon isn’t actually "dark," it receives just as much sunlight as the side that Earthlings can see.
Do the phases of the Moon affect the tides?
The Moon phases affect the height of the tides. During the Full Moon and New Moon phases, the Moon, the Sun, and the Earth line up, and the Sun’s gravitational pull is "added" to the Moon’s gravitational pull on the Earth. As a result, high tides are a little higher, and low tides are a little lower. During the First and Last Quarter phases, the Sun pulls against the Moon's gravitational pull, making the tides moderate: high tides are a little lower, and low tides are a little higher. See how the lunar tides work in our short video.
How long does each Moon phase last?
Technically, the four major phases (New Moon, First Quarter, Full Moon, Last Quarter) are actually very brief moments, even though they might appear to last a day or two to the naked eye. The remaining time is divided among the four intermediate phases (Waxing Crescent, Waxing Gibbous, Waning Crescent, Waning Gibbous). With the Moon's cycle lasting approximately 29.5 days, each of these additional phases spans around 7.4 days.
How do I know if the Moon is waxing or waning?
In the Northern Hemisphere, the Moon illuminated on the right is waxing, while the Moon illuminated on the left is waning. In the Southern Hemisphere, it’s the other way around. Also, the waxing Moon rises in the daytime and sets at night, while the waning Moon rises at night and sets in the daytime. Near the equator, the Moon appears to be "on its side," so the waxing lunar disk is illuminated on the bottom in the Northern Hemisphere and on the top in the Southern Hemisphere.
When does the Moon rise tonight?
Moonrise and moonset times depend on the current phase of the Moon, your location, and your time zone. You can find the exact rise and set times and other important information about our natural satellite in the stargazing app Sky Tonight.
Phases of the Moon: the key takeaway
The Moon goes through four major and four minor lunar phases in its 29.5-day lunar cycle. In this calendar, you can find the Moon's phase, age, illumination, and more for each day.
