It takes the earth 24 hours (1 day) to complete one rotation.
_____________
24 hours is a good estimate; rotation refers to earth's movement on its axis. But depending on how minutely accurate you want to be, even "24 hours" needs to be tweaked a little. When a point on the equator for example goes from one solar noon to the next, it has rotated slightly more than one full time. The earth's rotation and its orbit are going counter-clockwise. As a result the earth has to turn a little extra to put the sun in the same position as the previous solar noon. The 24-hour day is based on this solar day, averaged (hence the word "mean") over the year to give us Greenwich Mean Time. A sidereal rotation is relative not to the sun but to the distant stars, and will be a little less than a mean solar day. It will also be precisely 360 degrees. It will be roughly 23 hours, 56 minutes and 4 seconds.

∙ 10y agoIt takes about 23 hours and 56 minutes. That's a bit less than the 24 hours in a day, of course. That's because the day length depends a bit on the Earth orbiting the Sun, as well as its rotation period.

How long does it take for neptune to rotate around the sun once?
165 (Earth) years.
Why does a day consist of 24 hours?
because that's how long it take for the earth to rotate once
How long does it take the earth to travel once on its azxl?
It takes one day for the Earth to rotate once on its axis. It takes about 365.25 days for the Earth to travel (orbit) once around the Sun.
How long it takes for the moon to rotate once?
It rotates once in 27.32 days - the same time that it takes to orbit once around the Earth - which is why it always looks the same from Earth.
How long do planets take to rotate once?
It very much depends which planet you mean, as it depends on dozens of factors! Referring to Earth, it takes one day (24 hours) to rotate once around it's own axis.
How long it take for the earth to rotate once?
24 hours, approximately.
How often does Venus rotate?
Venus takes approximately 243 Earth days to rotate just once!
How long does it take to make the sun rotate around earth?
The Sun does not rotate around the Earth, nor does the Earth rotate around the Sun. The Earth revolves around the Sun each year, and each body rotates about its own axis: once a day for the Earth, once in about 25 days for the Sun.
How long it does take the moon to rotate?
Earth's moon does rotate on it's axis but it does it once each orbit of the Earth: every 27.3 days .
How long would it take for the earth to rotate once around its axis?
24 hours
How long does it take earth to rotate and orbit once?
about 24 hrs and 1 year
How long does it take for neptune to rotate around the sun once?
165 (Earth) years.
Why the ocean do not rotate and earth rotate?
The ocean and the earth do rotate. At the same speed, once every 24 hrs.
Why does a day consist of 24 hours?
because that's how long it take for the earth to rotate once
How long does it take the earth to travel once on its azxl?
