This leaves a light closer to the red spectrum, so a moon low on the horizon can sometimes appear more yellow or even pink than one directly overhead. Seeing a star with the Sun in the field of view will never be less difficult than spotting a handful of candles while looking into the beam of the most powerful spotlight on Earth.
The moon is far away compared to anything else you see when you drive, such as telephone poles that seem to fly past your car as you drive down the highway. Not only does the moon appear to change shape through an optical illusion, but it also appears to move across the sky.
Why are we unable to see the moon and other stars during the day?
So to photograph the Sun and have another star appear in the same image, your detector needs a dynamic range of 10 billion. The result is that the exposure times of most of the Apollo photographs were so short that the photographic emulsion never received enough light from the background stars to react. When the sun rises, the blue color of sunlight is scattered throughout the atmosphere, turning the sky the familiar bright blue color. At night, when the sun’s rays are blocked by the other side of the Earth, it is possible to see the faint light of stars shining in space.
Children are often taught to associate the sun with the day and the moon and stars with the night. To put the Sun and Moon on that scale and show them how far the magnitude system can go in the negatives. This blue light is much brighter than the faint light coming from the stars, so it prevents us from seeing them.
where is the moon during the day?
The time it takes for the Moon to rotate on its axis is the same as the time it takes to complete one trip (or “orbit”) around the Earth. In each phase, only part of the illuminated half is visible to the Earth, from 0 at a New Moon to 100 during a Full Moon. The opposite occurs before a Full Moon, when the Moon rises before twilight and is visible in the west in the afternoon and early evening before sunset. From the conjunction of these elements, you can sometimes see a beautiful, faint Moon hovering above the horizon.
If you observe the Moon for several nights in a row, you will notice that it is in a slightly more easterly position in the sky each night as it approaches the Full Moon, or wanes into a 0% illuminated New Moon. During the time of the Full Moon, the Sun and Moon are on opposite sides of the Earth, and the illuminated side of the Moon faces the night side of the Earth (see illustration). As the Moon continues in its orbit around the Earth, moving away from the Sun, more and more of its illuminated surface becomes visible. About 7 days before the full Moon, look to the eastern sky and you will see it rising in the evening.
So, around noon, when the Sun has already risen in the east and is at its highest point in the daytime sky, the Moon will be rising in the east. The Moon can sometimes appear in the sky during the day because it is the closest object to the Earth, and because its orbital cycle makes it sometimes brighter during the day than at night.
As mentioned above, the other reason for the Moon’s apparent brightness is due to the nature of its continuous orbit around the Earth. The maximum example of this is just before and after the new moon, when a crescent moon illuminated at 1stá in the sky, but very close to the sun, before sunrise (before the new moon) or after sunset (after the new moon).
Like most moons, ours is in synchronous rotation with the planet, which means that one side is constantly facing the Earth. The Earth’s daily revolution on its axis means that the Moon is actually above the horizon for about 12 hours out of every 24. The time it takes for the Moon to rotate on its axis is the same as the time it takes to complete one trip (or “orbit”) around the Earth.

The daily revolution of the Earth on its axis means that the Moon is actually above the horizon for about 12 hours out of every 24. The reason the Moon is brightest during the Full Moon is simply because during this phase it is exactly opposite the Sun.
Can the moon be seen during the day?
No. On the contrary, it is officially a Full Moon when the Moon is aligned with the Sun and the Earth while it is at the opposite end of its orbit, on the night side of the Earth. Even so, eclipses usually occur only one full moon in six; the other times the Earth’s shadow is either too high or too low to touch the Moon.
If you want more information about the Moon, check out NASA’s Solar System Exploration Guide to the Moon, and here’s a link to NASA’s Lunar and Planetary Science page. But we don’t see the Moon all the time during the day, and that’s because of where the Moon may be in the sky.
The Moon is visible in daylight almost every day, the exceptions being near the new Moon, when the Moon is too close to the Sun to be visible, and near the full Moon when it is only visible at night. If you have ever seen a Full Moon just after sunrise or just before sunset, chances are you have seen it at least one day before or after the actual Full Moon phase.
Likewise, the Moon will be well placed for daytime observing near first quarter, which will occur next Saturday in September. For 12 hours a day, the Moon is above the horizon, but its appearance may not coincide with daylight hours, so for any chance of observation, there is only a small margin of 6 hours.
The Moon is always half-illuminated by the Sun, but from the surface of the Earth it does not appear so. The best times of the month to see the Moon in daylight are near the first and last quarter, when the Moon is 90 degrees from the Sun in the sky. Near the new Moon it is too close to the Sun to be seen and when it is near the full Moon, it is only visible at night after the Sun sets. Secondly, there is the particular nature of the Moon’s orbit around the Earth, also known as the Lunar Cycle.
What phases of the moon are visible during the day?
A full moon rises around sunset, shines throughout the night, and sets around sunrise the next morning. This story prompted another reader to send in an alternative version for the origin of the name of the children’s moon. The Moon can be seen in the daylit sky in any phase except the new moon, when it is invisible to us, and the full moon, when it is below the horizon during the day. The phases from crescent to waning quarter are high in the sky during the day, but the diurnal gibbous phases can only be glimpsed just before the Sun sets.
I have heard that the diurnal moon was called the “children’s moon” because their eyes were sharp enough to distinguish it, while the old people, with diminished eyesight, could not distinguish it from the clouds. While the Full Moon phase is technically a specific moment in time, the instant of syzygy, the Moon is seen fully illuminated for a few days before and after the actual alignment, during the last stages of the waxing Gibbous Moon and the beginning of the waning Gibbous Moon.
I am an experienced science, technology and travel journalist and stargazer who writes about night sky exploration, solar and lunar eclipses, Moon watching, astronomical travel. And at night, the Moon (when visible) is the brightest object, sometimes to the point that it can make it difficult to observe the Milky Way and deep sky objects.
The Moon’s revolution around the Earth makes the Moon appear to change shape in the sky. For example, the New Moon phase occurs at the exact moment when the Moon is between the Sun and the Earth, and the three bodies form a more or less straight line. This leaves behind a light closer to the red spectrum, so a moon low on the horizon can sometimes appear more yellow or even pink than one directly overhead.
