The superstructure is also called the Southern Great Wall, the Great Southern Wall, or just the Southern Wall, in reference to the Northern Great Wall. The structure is 8000 km/s long (where km/s indicates the rate of expansion between two objects at the extents of a superstructure), 5000 km/s wide, 1000 km/s deep, in redshift space dimensions.[3][4] Because these structures are so large, it is convenient to estimate their size by measuring their redshift; using a value of 67.8 for Hubble's Constant, the size of the structure is approximately 100 Mpc long by 70 Mpc wide by 10 Mpc deep.
