About 220 km/sec.
Well, isn't that just the most lovely question! You see, everything in our Milky Way galaxy spins peacefully like a gentle dance in the meadow. The Milky Way itself also gracefully twirls through space at a speed of about 220 kilometers per second. Just take a moment to appreciate the beauty of it all. Everything is right where it should be.
If you mean "rotate", yes, it rotates. If it didn't rotate, it would soon collapse due to its own gravity. Our Solar System takes about 240 million years for one revolution around the Milky Way - at a speed of 220 kilometers/second.
Well, isn't that just a beautiful mystery of the universe? The solar system gracefully moves through space at an average speed of about 515,000 miles per hour as it orbits around the Milky Way galaxy. Just imagine all the happy little stars and planets dancing together in harmony, creating a wondrous celestial masterpiece for us to enjoy from down here on Earth.
That will depend on the speed of our spacecraft. At its current speed, the Voyager spacecraft will not make it out of the Milky Way galaxy within the expected lifetime of the universe, and certainly not before the Andromeda galaxy collides with the Milky Way galaxy about 3 billion years from now. In another thousand years, after we've had some time to study this, ask me again.
The Milky Way galaxy takes about 200-250 million years to complete one full rotation. This rotation speed varies based on the distance from the center of the galaxy, with stars closer to the center orbiting faster than those further out.
even at th speed of light it 2,000,000 (2 million) years away!!!!!!!!!!!
The sun is in an enormous orbit around the center of the Milky Way galaxy. It is estimated that it takes between 225 and 250 million years for the sun to make one orbit, called a galactic year. We are traveling around the center of the galaxy at a rate of about 220 km/second, which is .073% of the speed of light.
The Andromeda Galaxy is moving towards our Milky Way galaxy at a speed of about 110 km/s. This movement is called the "Andromeda-Milky Way collision." Scientists predict that the two galaxies will collide in about 4 billion years, merging into a single galaxy.
The sun revolves around the center of the Milky Way.
Possibly... but we are pretty sure that in approximately 3 billion years we will colide with the Andromedia galaxy which is the galaxy closest to the milky way (our galaxy). We are (our galaxy) speeding tward the Andromedia galaxy at the speed of light.
Relative speed is 0 m/s i.e. with respect to Earth as ftrameIn frame out side the Milky way::The earth also has a speed in its orbit around the sun (average around 30 km/s). Added to this is the speed of the solar system orbiting the centre of the Milky Way Galaxy, and the speed of the galaxy as it moves through space. I believe that these latter two currently combine to around 260 km/s. Note, though, that you can't just add the 30 km/s speed of the earth in its orbit around the sun to 260 km/s since the direction of the earth's travel around its orbit is constantly changing.
Any such speed must be specified with relation to something: for example, with relation to the Andromeda Galaxy, the average of the Local Group, of the Local Supergroup, etc. There is no such thing as an "absolute speed".
