how fast is the earth spining/traveling?

Answer 1

Earth's rotation is one turn per 24 hours.
Circumference is 40,000 km (I'm keeping to round figures here) so that the speed at the equator is 1666.67 km/h or 0.463 km/s (towards the local East).

If you are at a different latitude, your speed is 0.463*Cos(LAT).

Earth orbits the Sun at an average speed of 29.786 km/s (a lot faster than the speed due to spinning).

Because our spin axis is tilted relative to our orbital plane (by 23.4393 degrees -- it is called the obliquity), your speed relative to the Sun is the sum (or difference) of the two:
At noon: 29.786 - 0.463*Cos(LAT)*Cos(23.4393)
At midnight: 29.786 + 0.463*Cos(LAT)*Cos(23.4393)
both in km/s

We have looked at hundreds of stars very close to the Sun to estimate the "normal" orbital speed of stars around the Galactic centre. We assume that the Local Standard of Rest (the normal orbital speed at our position in the Galaxy) is the average of all our neighbour's orbital speeds.

Relative to the LSR, the Sun is moving at 19.4 km/s in the direction of the constellation Hercules. This direction is approximately 53 degrees from the ecliptic (i.e., not at all in the same direction we orbit the Sun).

Our speed will vary between these extremes:
19.4 +/- [29.786 +/- 0.463*Cos(LAT)*Cos(23.4393)]*Cos(53)
in km/s
where +/- means "plus or minus": you solve the equation using plus and find one value; you then solve it again using minus to find another value. You do this with all +/- signs to find the extremes.
So far, we have found our speed relative to the average of our neighbourhood stars.

The LSR orbits the Galactic centre at 230 km/s relative to the centre of the Galaxy. This speed is far greater than all the small stuff we have calculated so far.

Our Galaxy appear to be moving, relative to the Cosmological Microwave Background radiation, at a speed of approximately 400 km/s, in the general direction of the constellation Hydra (near its border with Virgo).

Therefore, our total speed is somewhere around 500 to 600 km/s, with only 30 km/s of that being due to our spinning and traveling around the Sun.

Answer 2

Spinning at 1667 kph at the equator, orbiting at 30 km/s around the Sun, which is orbiting the centre of the Galaxy at around 67000 kph. The Galaxy and its contents are all moving towards a region of space called the Great Attractor at 700 km/s. Space is also expanding, so stationary points are moving away from each other at a speed depending on the distance between them.

Answer 3

The Earth is spinning around its axis. At the equator, the Earth's surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr or 0.5 km/sec). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24). As you move toward either pole, this speed decreases to almost zero (since the circumference of the spinning circle at the extreme latitudes approaches zero). The sun is about 26,000 light-years from the center of the Milky Way Galaxy, which is about 80,000 to 120,000 light-years across (and less than 7,000 light-years thick). We are located on on one of its spiral arms, out towards the edge. It takes the sun (and our solar system) roughly 200-250 million years to orbit once around the Milky Way. In this orbit, we (and the rest of the Solar System) are traveling at a velocity of about 155 miles/sec (250 km/sec).

Answer 4

As Astronomers know, the Earth does not orbit the Sun, the Earth and Moon in combination Orbit the sun.
You can imagine a fat wrestler and a tiny girl dancing around the edge of a large ball room, spinning slowly as they circuit.
At times the wrestler is going backwards relative to their joint forward motion, and at other times, he is going forward faster than their average motion. To all of the speeds mentioned so far, we add and subtract a lunar monthly plus minus of 42km/hr.

Answer 5

more importantly... relative to what ???

Relative to me as I write this its not. Speed has no particular meaning without a reference point and absolute velocity is still a hotly debated point with current best guesses revolving around velocity relative to background cosmological radiation.

Relative to the core of the Earth the surface is moving at around 1000mph give or take.

Relative to the Sun, the center of the earth is moving at around 30km/s, with any given point on the surface moving at ~30km/s +/- ~0.5km/s.

For any other reference point, the speed has the same pattern. Relative to the Galactic center its around 230km/s +/- (~30km/s +/- ~0.5km/s) but the further away you move the reference point the fluffier the figures get.

Check NASA's web-site for a fairly simple description of the dynamics.

Answer 6

it takes 24hours to spin once ( a day)
it takes 365 days to go round the sun ( a year)

Answer 7

At its equator, the Earth rotates at a speed of 465.11 m/s.
In its orbit around the sun, it travels at an average speed of 29,783 m/s.
Add to that the solar system's orbital speed around the galactic centre - 2.17 x 10^5 m/s.

Answer 8

The earth is spining at 0.5 km/sec while is traveling 29.8 km/sec around the sun.

Answer 9

I revolution per day, or about 1,000mph at the equator. On the bigger scale it's travelling once around the sun per year, which makes umm... 93 million miles times Pi = about 33,000mph around the sun.

Answer 10

It travels at around at about 29km/s.
The Earth spins around at about 1000mph though.
