How long does it take the earth to spin once of its axis?

Answer 1

23 hours, 56minutes and 4.091 seconds. This is the rotational period relative to the background stars, slightly short of the 24 hour apparent day. This is due to the time difference caused by Earths progression around the sun in that time, The earth has to carrying on spinning for a slightly longer time for the sun to appear in the same place again.

Answer 2

The time it takes the Earth to rotate once is called a day (24 hours).

The actual rotation time is a little less, about 23 hours and 56 minutes. But the "solar day" is longer, almost exactly 24 hours, because of the distance the Earth moves in its orbit around the Sun. The Earth has to turn that extra 4 minutes to again directly face the Sun.

The mean solar day, that is the average time it takes for the sun to go from its highest point on a given day to its highest point the next day, is 24 hours. If you measure the time it takes a distant star to reach its highest point (the sidereal day), it is 86,164.091 seconds (or: 23 hours, 56 minutes, 4.091 seconds). The difference is the apparent motion of the Sun, which is really caused by the Earth moving around it .
It takes the Earth 23 hours and 56 minutes and 4 seconds to make a full rotation. It takes 365 days to rotate around the Sun.
23 hours 56 minutes 4 seconds
24 hours, or a day

_______________________________

The Earth rotates in exactly 23 hours 56 minutes. The "day" is 24 hours, or 4 minutes longer. Why the difference?

Because the Earth is continuing around in its orbit, and it takes an extra 4 minutes for the Earth to spin enough so that it is facing the Sun with the same orientation. A "day" with respect to the Sun is a "solar day" of 24 hours. A day with respect to the stars is a "sidereal day" of 23 hours 56 minutes.
One day; about 24 hours. To be precise, 23 hours 56 minutes 4 seconds.
24 hours on its axis.
It takes earth just short of one 24 hour day. The actual time is 0.99726968 days. This equals one sidereal day.
Roughly 3minutes 56seconds less than 24 hours.
24 hours.
The time it takes the Earth to rotate once is called a "sidereal day". The actual rotation time is about 23 hours and 56 minutes.

The mean "solar day" is longer, exactly 24 hours, because of the distance the Earth moves in its orbit around the Sun. This orbital motion causes the small daily apparent motion of the Sun to the East in the sky. Of course, the Earth's spin causes the Sun's daily westward apparent motion.

So, the mean solar day, the average time it takes for the Sun to go from its highest point on a given day to its highest point the next day, is 24 hours.

If you measure the time taken for a distant star to reach two successive highest points in the sky (the sidereal day), it is 86,164.091 seconds (or: 23 hours, 56 minutes, 4.091 seconds). Take those 4 minutes a day, each day for a year, and it adds up to one "extra" day, or spin.
Exactly one day. The reason we have days is because the earth rotates and points to or away from the sun.

Actually it is just over 23 hours, 56 minutes and 4 seconds (which is 86164.09054 seconds).

During this time, the earth has moved a bit in its orbit around the sun, which is why it has to spin a little bit further to get back to facing the sun after 24 hours.
By definition it takes one day.

23 hr 56 min 4.1 sec even though a solar day is almost exactly 24 hours

We think of a "day" as being 24 hours. However, Earth is also orbiting the Sun, and after the Earth has rotated exactly one time in 23 hours and 56 minutes, it takes the Earth another four minutes to rotate enough to compensate for the Earth's movement in its orbit.
about 24 hours
24 hours or 1 day
24 hours.
Roughly 4 minutes less than 24 hours.
it takes about one day
It takes just a bit less than 24 hours which is the solar day. It rotates in about

23 hours and 56 minutes.
You might think that it takes 24 hours for the earth to turn on it's axis but really it's not. The earth takes 23 hours 56 minutes and 4.1 seconds to turn on it's axis.

it takes 24hrs

It takes about 23 hours and 56 minutes for the Earth to rotate completely once on its axis.

So, you ask, why is a day 24 hours and not 23 hours and 56 minutes? It's because during a day the Earth moves about a degree in its orbit around the Sun, so the relative position of the Sun changes in a way that makes the Earth have to turn a little bit more than one complete rotation in order to bring the Sun back to the same position relative to an Earthbound observer.
