Local Supercluster

The Virgo Supercluster
is a vast assemblage of
relatively small groups and
large clusters extending
more than 50 million light-
years from its center in the
massive Virgo Cluster. This
illustration is centered on
the Local Group and shows
all groupings that contain
at least three relatively
large galaxies. The size of
each sphere reflects the
number of galaxies in the
group or cluster. Distances
are shown in light-years (ly).
