Andromeda : Earth's closest Galactic neighbour
> Andromeda is a spiral galaxy and also our closest neighbour.
> It appears as a fuzzy patch of light and contains millions of stars.
> It is the farthest object that can be seen with the naked eye.
> Along with the Milky Way, it belongs to a group of galaxies known as the Local Group, which in turn is a part of Virgo Cluster of groups.
> Like stars, galaxies are grouped into clusters. Some clusters contain thousands of galaxies.
>About 30 galaxies, along with the Milky Way and the Andromeda are grouped together in one cluster called the Local Group.
>Clusters may group together into upper clusters.
> Super clusters are also spread randomly throughout the universe.
