How much does the earth rotate in one second?

Answer 1

Earth takes 365 days to rotate around the sun. Which leads to one year. 24 hours leads to one day!

Hey peoples!

How is everyone?

Well I hope I answered your questions

Bye

adios

I love pie

I know I am out of the question

hahahha

lol

omg

bye!

Answer 2

The length of time it takes for the earth's rotation about its axis is 23 hours, 56 minutes, and about 4 seconds. This is called a sidereal day. This is different than a solar day, which is the time interval measured between successive noon's and is 24 hours.

Answer 3

Approximately 366.24 rotations per year. The additional rotation above 365.24 (the number of days/year) makes up for the phenomenon that without any rotation, there would be 1 day/year and the sun would rise in the west and set in the east.

See Sidereal time for more detail.
365.25

Every rotation of the earth is a day for us. The .25 is made up in leap years

Answer 4

360 degrees in 24 hours = 15 degrees per hour = (15 / 3,600) = ( 1/240 ) degree per second

= 0.25 minute of angle per second = 15 seconds of angle per second.

At the equator, the linear speed is something like 1,520 feet (0.29 mile) per second.

At latitudes separated from the equator, the linear speed decreases as the cosine

of the latitude.

Note: All of these numbers are only approximate, since the earth's period of rotation is actually

about 4 minutes less than 24 hours. But they're pretty close.

Answer 5

It takes 24 hours for the earth to make a complete rotation.

It may sound like the earth is moving very slow, but its extremely fast.

That is why we see the sun and stars rise and set from east to west.

Answer 6

Move relative to what?

If we assume the Sun is fixed and only take into account the Earth's orbital motion, then it's a bit under 30 kilometers (I get 29.85 and change in my quick back-of-the-envelope calculation).

However, the Sun (and the rest of the Solar System as a whole) is rotating around the galactic barycenter at (very, very roughly) 20 km/second, and the Milky Way as a whole is moving at (again, very roughly) 600 km/second with respect to something called the "Hubble flow" (look it up, I can't do everything for you) and at about 550 km/second with respect to the photons of the cosmic microwave background radiation (in the general direction of the constellation Hydra).

So "relative to what" is a very, very important question here.

Answer 7

{- it is 365 because there are 365 days in a Year so the answer is 365!}

'365.2564 rotations -once everyday!'

Nope, 366.25. The Earth takes 23 hours and 56 minutes to make a complete rotation.

Because we are revolving around the sun, it takes a little extra rotation to get the sun back.

Answer 8

The Earth rotates approximately 0.0007 degrees in one second. This means that it completes one full rotation on its axis in about 24 hours.

Answer 9

1/86,400th of a revolution. How fast that is in, say, miles per hour depends on your latitude. At the equator it works out to a bit over 1000 mph; at the pole it's pretty much zero.

Answer 10

About 365 1/4. The exact length of a year varies, depending on what you use as a reference point.
