A) the Virgo Cluster
B) the Great Wall
C) the Local Group
D) the Taurus cluster

Question

Quizplus · Accepted Answer

The Virgo Cluster is a nearby galaxy cluster that contains at least 1,300 galaxies in a region about 5 Mpc (16 million light-years) across. This makes it one of the closest and largest galaxy clusters to our own Milky Way galaxy. The Great Wall is a large-scale structure of galaxies that extends over a much larger distance of about 500 million light-years and is not localized to a region 5 Mpc across. The Local Group is a group of galaxies that includes the Milky Way and several nearby galaxies, but does not contain 1,300 galaxies within a region of 5 Mpc. The Taurus cluster is a relatively small and distant galaxy cluster that is not known to contain at least 1,300 galaxies within 5 Mpc.
