Local Hole

(KBC Void)
(void containing the Local Group)

The name Local Hole (aka KBC Void) has been coined for a large region of space of relatively-low density (i.e., a void) that surrounds us, on the order of 600 Mpc across: including the Local Group and basically including the much or all of Laniakea Supercluster. (Voids are the low-density regions of the universe, but they are not free from galaxies, etc.) I presume the high-density regions which distinguish this void would be the galaxy filaments that surround us. This is a far larger structure than what is termed the Local Void, which is on the order of 60 Mpc across.
