How Fast Is Milky Way (through space)?

Our entire galaxy is hurtling through space at 600 km/s, pulled by something called the Great Attractor — a mysterious mass concentration we can't directly see. Even our entire 200-billion-star galaxy is just along for the ride.

The Great Attractor is hidden behind the Milky Way's own galactic plane — making it one of the largest structures in our cosmic neighbourhood that we still can't directly observe.
