The Earth travels in its orbit around the Sun at about 18 miles per second on average (67000 miles per hour). The speed varies depending upon how close the Earth is to the Sun. The closer it gets the faster it goes. The distance to the sun varies from about 90,000,000 million miles in December to about 94,000,000 in June.

All points on the Earth rotate once per day, except the north pole and south pole, the two points which do not move and which define a line around which all other surface points rotate. Those points closest to the poles move the most slowly (inches per day), while those on the equator must move at over 1000 miles per hour.

Points on the equator have the fastest distance to travel, so they move fastest. Points at the pole move slowest.

The circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour.

I think it depends on where you are. The top will twirl faster than the middle. The circumference of the Earth at the equator is 24,900 miles or about 25,000 miles and the Earth rotates about once in 24 hours. Therefore, if we divide 25000 by 24 we get that the earth rotates at a speed of just over 1000 miles per hour.

Also, the Earth is orbiting around the Sun at about 67,000 miles per hour.

The IERS defines the "excess of length of day (LOD)" as the difference between the duration of the mean solar day and 86,400 SI seconds [1]. Excess of Length of Day since 2000

while each and every of the timber are shrink down the hassle-free radius of the earth will advance via means of an extremely negligible volume of the order of 10^-8 or 10^-9.this transformation won't make the earth to rotate lots rapid by using fact the mass of the earth is relatively great.Even the substitute in velocity is relatively small it won't be in a position to be measured in any respect.

I presume you are asking about the rotation of the earth about its axis.In that case,the speed varies with latitudes.At the equator ,the rotational velocity is 465 metres per second or 1674 Km per hour.

the earth spins at 1 spin/day. it revolves around the sun at 1 rotation/year

Earth makes 1 round per day. the distance the point, with the fastest tangential component of velocity, travels is 2*pi*R,
where the radius is
R=6,378.135 km (3,963.189 mi)
pi=3.14
and that point is on equator
the time is 24 hours

so the speed will be (2*pi*R)/time (in km/hr)

Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour,
That's orbiting at nineteen miles a second, so it's reckoned,
A sun that is the source of all our power.
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour,
Of the galaxy we call the "Milky Way".

approximately 1,000 miles an/hour (Earth's rotation)

The Earth orbits the sun at 67,000 miles an/hour

i heard it was like 20 miles a second
