a fraction of a second ... but usually a single day (or night) it's close enough.
But it looks full for about 3 days
technically, a full moon represents the instant that the moons shadow completely disappears because of it's alignment with the earth and the sun. This is known as a lunar phase. On average, humans can not determine the exact moment this lunar phase occurs without the aid of a telescope. Therefore, the full moon appears to remain full for a period of 36 hours - 18 hours before this lunar phase and 18 hours after - to the naked eye.

∙ 13y agoThe answer to this question depends on how we measure a "day". If we think of a day as the amount of time it takes the moon to rotate 360oon its axis, then one lunar day is about 27.32 Earth days long. However, if we consider the perspective of an observer standing on the moon, then a day is the amount of time between two sunrises (or sunsets, or noons; from any point, around and back to the same point). In this case, a lunar day lasts about 29.5 Earth days. This is usually the definition that astronomers prefer.
Nighttime on the moon lasts about 14 Earth days. This is due to the moon's slow rotation, which causes the same side of the moon to face Earth for an extended period of time. During this time, temperatures on the moon can drop significantly.

∙ 15y agoEach "day" - from Sunrise to Sunrise - on the Moon is 29.5 days.
The Moon actually spins in 27.3 days, but because the Moon is also circling the Earth, the lunar "day" is a little different.

∙ 15y agoThe position of the moon is constantly changing, so in reality it is only full for an instant. To us it usually looks full on just one night and very close to full on the nights closest to that. Some calendars give the dates of the different phases of the moon and if you carefully observe it on and around those dates, you will notice a slight difference each night.

∙ 12y agoIf you stay in one place on the moon and don't move around, you have the sun
up in your sky for 14.77 Earth days, followed by the sun down and invisible for
the next 14.77 Earth days. So, roughly 2 weeks of day and 2 weeks of night.

∙ 14y agoWhat's a day on the moon ? The length of time between two sunrises in the same place ?
If that's what a day is, then it's 29.531 earth days, or 2,551,478 seconds (rounded).

Equatorial circumference = pi D = 24,900 miles.
Average earth-moon distance is listed as 238,856 miles = 9.59 times earth's circumference

∙ 9y agoJanuary is the month of the Full Wolf Moon. It appeared when wolves howled in hunger outside the villages. It is also known as the Old Moon. To some Native American tribes, this was the Snow Moon, but most applied that name to the next full Moon, in February.

What phase is the moon in when you cant see it in a clear nighttime sky?
new moon
Name something you associate with a full moon?
Astronauts Craters Stars Man in the moon Rocket Cheese Eclipse Loonies (from Lunar) nutters, silly people. Spring Tides Warewolfs
How long are the days on the moon?
Days on the moon are 29.531 earth days long.
Is lunar phase visible at midnight?
Yes, lunar phases are visible at midnight. Depending on the phase, the moon may be high in the sky or lower, but it is still visible during nighttime hours.
What planet is the brightest planet in Earth's nighttime sky?
Venus is the brightest planet in Earth's nighttime sky. It is often referred to as the "Evening Star" when it appears in the west after sunset and the "Morning Star" when it rises in the east before sunrise.
If the Moon rotates in 28 days how long would nighttime last if you were on the Moon's equator?
Nighttime would last for about 14 Earth days if you were on the Moon's equator, as the Moon's rotation period is 28 days. This means that one full rotation of the Moon would result in 14 days of daylight followed by 14 days of nighttime.
What is the symbol for nighttime and daytime?
The symbol for nighttime is typically a moon, while the symbol for daytime is typically a sun.
What planet is closest to the moon at nighttime?
Earth.
What phase is the moon in when you cant see it in a clear nighttime sky?
new moon
What do you call part of moon which is away from sun?
nighttime or darkside
How long is daytime and how long is nighttime?
24
How is Moon's light helpful to nighttime prowlers?
It helps them see at night better.
Does the moon have daytime and night time?
Like the Earth, the moon rotates on its axis. This means that the surface of the moon has a sunlit and sunless time. This creats a lunar day and night. The lunar day/night cycle is about 28 Earth days long.
Does the moon have daytime and nighttime?
No, the moon does not have daytime and nighttime like Earth. Instead, the time when you can see the moon depends on its position in relation to the Sun and Earth. When the moon is on the side facing the Sun, we see it as fully illuminated (full moon), and when it is on the side facing away from the Sun, we see it as not illuminated (new moon).
Would it be hard to build a colony on the moon?
Yes. it is very hot in the daytime and very cold in the nighttime.
Can you see the moon on the other side of the earth from Egypt?
No, because the moon orbits the Earth. If you are in Egypt and it is nighttime, the moon would likely be visible somewhere in the sky above you, not on the other side of the Earth.
What makes nighttime on the moon cold?
The lack of atmosphere on the moon means there is no blanket of air to trap heat, so temperatures drop drastically during the lunar night. Without an atmosphere, there is also no mechanism for redistributing heat, leading to extreme temperature differences between day and night on the moon.
