how fast is the sun moving?

Question

does it have a rotation about it's own axis? and how fast is it moving relative to the other stars, and how fast is it moving relative to space in it's entirety. that should include how fast it's orbiting around the milky way, and how fast the milky way is moving

Answer 1

It rotates once every 25 days. There is no such thing as speed relative to space so absolute speed is not very meaningful. There are no fixed reference points in space.

The sun goes around the milky way once every 250 million years which is 217 km/s.

Relative to nearby galaxies we are travelling at 600km/s relative to the cosmic microwave background.

Answer 2

You have a few misconceptions about motion and the universe that need to be cleared up.

First, you cannot ever ask how an object is moving relative to "space itself", because space ITSELF has no measureable velocity. Rather, things move within space-time, and the best you can ever do is look at objects moving relative to other objects -- not in absolute terms.

So the speed of the Sun depends on your frame of reference. From the perspective of the Solar System as a whole, the Sun is not really moving; that's not very surprising, since the Sun's gravity keeps the Solar System organized as it is. If you look at the perspective of the complete Milky Way Galaxy, the Sun is located about 2/3 of the way from the centre and is orbiting the galactic core. In this orbit, the sun travels one light-year every 1400 Earth years, and it completes a revolution of the galaxy every 100,000 years or so.

If you look at the Sun from the perspective of other galaxies, the relative motion of those galaxies and ours comes into the equation, so the speed varies depending on which galaxy you look at.

The same can be said about galactic clusters, and also about galactic superclusters.

In the other direction, you can examine the Sun's motion from Earth; in this case you see the Sun moving in an elliptical (almost circular) path every 365.24 days at an average distance of about 150 million kilometres.

Answer 3

The Sun is moving with the earth atached to its system relative to a star about 12. 5 miles per seconds or 20 km/sec .Galaxies have been noted to move at 200 km /seconds. The recession velocity of the Universe have be observed to be as high or higher than the speed of light.
However to measure distance traveled over time period traveled you need a fixed point in space that point is called the zero reference point by some renoun physisits. The is the point wwhere you start your measurement. So all measurements start with zero .

Answer 4

Theres no way of knowing how fast we or the sun are moving, we can only measure how quickly other galaxies are getting away from us.
