Supercluster Virgo The supercluster we live in is known as the Virgo Supercluster. It’s an enormous collection of more than a million galaxies, stretching across a region of space 110 million light-years across.

Our Cluster or Galaxy Group Local Group Our Sun is just one member of the Milky Way, and the Milky Way is part of a collection of galaxies known as the Local Group. This contains three large spiral galaxies: the Milky Way, Andromeda, and the Triangulum Galaxy, as well as a few dozen dwarf galaxies.

More than one million planet Earths could fit inside our Sun, but compared to the monumental masses we find in the rest of the galaxy, our Sun is somewhere in the bottom half in terms of size. Its stellar classification puts it at a Type ‘G’, also known as a yellow dwarf, which is about 15 times smaller and 60 times less heavy than an average Type ‘O’, commonly called a blue supergiant.
