ELI5: Are we travelling at the speed of our galaxy?

Or does our solar system travel at a different speed?

The galaxy itself is also rotating a little bit, so you could say the solar system is also rotating around the galaxy in that sense. Otherwise, yes. We could be considered to be travelling at the speed of the galaxy, relative to other galaxies (with tiny fluctuations from various sources).

It isn't particularly insightful, though. Since movement is relative, it doesn't really matter how fast we would want to think we are moving. It just depends on how we are moving relative to other things.
