In the Milky Way, stars can move as fast as 500 kilometers per second if they live in the halo, or in the nuclear regions of the Milky Way, or as slowly as a few kilometers per second if they live in globular clusters. Of course, all motion is relative so we have to specify what our local standard of rest is. For the halo/core stars we can choose the core of the Milky Way, for globular clusters it is the center of mass of the cluster. Our own Sun is moving through space at about 30 kilometers per second in the direction of the star Vega. Of course, the entire solar system is moving with this same speed and direction so we experience nothing out of the ordinary except that astronomers notice a small but systematic parallax due to the solar motion. In 10 years, the sun's motion towards Vega amounts to about 900 million kilometers. The corresponding parallactic angular shift can be seen in the positions of nearby stars.
