how quickly is the milky way relative to the cosmic backround radiation on its way through the universe ?
I mean not the rotation speed
thank you

When the Earth's velocity around the Sun has been taken into account the Solar System is traveling at 390 +- 60 km/sec relative to the surface of last emission of the CMB. However when the Sun's motion around the Galaxy is also taken into account this translates into the fact that the Galaxy is traveling relative to the surface of last emission of the CMB, which probably defines the C.M. reference frame of the universe, at 603 km/sec or about 0.2%c!

The speed of the Milky Way galaxy is approximately 1.3 million miles per hour, or 2.1 million kilometers per hour. This speed is relative to the cosmic microwave background radiation, which is the leftover radiation from the Big Bang.
The speed of the Milky Way galaxy is measured using a technique called redshift. This involves measuring the slight change in light wavelength from distant objects due to the expansion of the universe. The greater the redshift, the faster the object is moving away from us.
No, the speed of the Milky Way galaxy is not constant. It varies depending on the location within the galaxy and the gravitational forces acting on it. For example, the outer parts of the galaxy may be moving slower than the central bulge due to the pull of the galactic center.
The speed of the Milky Way galaxy is relatively average compared to other galaxies in our local group. It is not the fastest or the slowest, but it is constantly changing due to the dynamics of the universe.
Yes, the speed of the Milky Way galaxy can change over time. This is due to the interactions with other galaxies and the changing gravitational forces within the universe. It is also possible that the speed of the galaxy may increase as it continues to merge with other galaxies in the future.
