How long is nighttime on the moon?

Answer 1

The 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.

Answer 2

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.

Answer 3

The diameter of the moon is about 2,161 miles or (3,476 kilometers). This makes the circumference about 6,790 miles. As you see the moon is small when its circumference is only 6,790 when the earth which has a circumference of 24,859 miles .

Answer 4

Lunar month is of twety nine and half days brokn into two equal parts of ascend and descend, each of 14 days terminated by full moon and new moon lternatively. Logically full moon is for less than a day by couple of hours.

Answer 5

Each "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.

Answer 6

The 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.

Answer 7

If 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.

Answer 8

What'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).

Answer 9

Earth's equatorial diameter is listed as 7,926 miles.

Equatorial circumference = pi D = 24,900 miles.

Average earth-moon distance is listed as 238,856 miles = 9.59 times earth's circumference

Answer 10

January 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.
