How long does it take for earth to spin on its axis?

Answer 1

Just over 23 hours, 56 minutes and 4 seconds (86164.09054 seconds).

It takes almost 24 hours for the Earth to rotate once. But during this time, the Earth has moved slightly in its orbit, which is why it has to spin more (a full 24 hours) to get back to the same position facing the Sun (a "solar day")

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 . Take those 4 minutes a day, each day for a year, and it adds up to one "extra" day, or spin.

The period of Earth's spin (rotation) is just over 23 hours, 56 minutes and 4 seconds (86164.09054 seconds). (This is called the "sidereal day.")

The reason that it takes 24 hours for a place on Earth to be exactly facing the Sun again is that the Earth is moving in its orbit around the Sun at the same time. So it has to spin a bit more to get back to directly facing the Sun.

It takes the earth roughly 24 hours to spin on its axis.
24 hours
It takes 3minutes 56seconds less than 24hours for the Earth to spin (rotate) once on it's axis.

It takes 365.2422days for the Earth to revolve once around the Sun.
One completer spin takes 23hours 56minutes 4seconds. (rounded)

Answer 2

You might think that it takes 24 hours for the earth to turn exactly 360 degrees on its axis but that isn't quite right. The earth takes 23 hours 56 minutes and 4.1 seconds to complete exactly one 360 degree turn on its axis. This is the sidereal period of rotation. The synodic period of rotation (earth returning to the same alignment relative to the sun) is 24 hours, or what we casually call one day. These periods are indeed different, and it is not easy to wrap your brain around it; it goes against what your intuition tells you. But for just one effect, that tiny difference is the reason why different constellations appear in the same part of the sky at the same time of night in different weeks.

Answer 3

One complete turn on its axis takes 24 hours, or one day.

To be more precise it takes about 23 hours 56 minutes. It's a bit less than

the 24 hours of the "day"( which is the "mean solar day").

Answer 4

It takes the earth several thousand years to tilt on its axis. The actual number amount of years varies and is still unknown.

Answer 5

One complete rotation of the earth's axis is called a "day".

Answer 6

it takes a day (24 hours) to be exact!

Answer 7

3minutes 56seconds less than 24 hours.

Answer 8

The Earth spins on its axis for 24 hours

Answer 9

THE EARTH 365 DAYS
