Great Attractor

(gravity anomaly at the center of our supercluster)

The Great Attractor is a spot in space on the order of 200 million light-years away, apparently with the mass of many thousand galaxies. It is the center of Laniakea Supercluster, our local Supercluster. It is evident from Redshift (z) surveys, that show peculiar velocities of galaxies in the range of +700 km/s to -700 km/s.
