the earth moving on its axis at certain speed.the earth rotates around the sun at certain speed.?

Question

the solar system rotating aroung the milky way galaxy in certain speed.and the milky way galaxy is traveling toward some direction at certain speed.at what speed are we travelling very second through the universe

Answer 1

The rotational speed at the Equator due to the Earth spinning on its axis is 1080 miles/hour (mph). The speed of the Earth in its orbit around the sun is 67,000 mph. The speed of the solar system as it travels around the center of the revolving Milky Way Galaxy is 560,000 mph. These speeds are not additive like linear velocities because they are rotational and in different plans.
The actual path described by these combines rotations and translations as seen from deep space would be a complex series of loops and zig zags. The speed of the Milky Way through space is undetermined because speed is relative to a point of reference. There is none other than the Hubble Constant for the expansion rate of the whole universe.

Answer 2

Earth is spinning on its axis (not moving) and Earth is revolving around the Sun.

Milky Way spins on its axis and the center of which is a massive Black Hole.

We are part of Milky Way and hence this is the 3rd dimensional traveling.

The entire Milky Way is assumed traveling in the universe and we fear collision with Andromeda Galaxy, which is traveling towards Milky Way at an extremely large speed. Don't worry, the collision is still away in Millions of years.

So, simplifying again on all traveling -

1. We spin as Earth Spins on axis
2. We travel as Earth revolves around the Sun
3. We spin as Milky Way spins
4. We travel as Milky Way travels in the universe

Now, just calculate how much distance we travel in our life span. It cannot be measured for sure.

Answer 3

Es ist alles relativ.

With reference to what zero(starting/fixed) point is the measurement being made?

eg. 1000 miles per hour may be said to be the speed at which the earth rotates about the sun. But in truth you are asking for velocity, which varies from moment to moment in the absolute magnitude of its summational vector.

1000 miles per hour is a good one to quote, especially since we do not move outside the solar system, let alone the milky way galaxy, so in a sense such movements do not occur for us (and may indeed be but an artifact of our current level of knowledge rather than a demonstrable truth in the absolute).

Answer 4

Solar system is a part of Milky way, how come it rotates around milky way ?

Answer 5

First of all, there is no "certain" speed for any of the things you mention. The speeds are changing faster or slower all the time.

The Earth is moving at *about* 375 km/s through the universe. But during each year it is sometimes 345 km/s, sometimes it is 405 km/s.

Answer 6

It's all relative.

And for a previous answerer, our solar system DOES orbit around the center of the galaxy since it is located out in one of our galaxy's spiral arms.
And just like another answerer said, what frame of reference are you using. One person could observer you sitting in front of your computer and say you are not moving, your speed is zero. Another person out in space could say you're zipping along at the speed of the earth's rotation which is approx 1000mph at the equator. So, one observer says you have zero speed and another says you have a speed of almost 1000mph. Which observer is correct? Simple, thanks to Relativity, they are both correct relative to their respective frame of reference.
