Earth is in milkyway galaxy which is part of Virgo cluster and Virgo cluster is located in Virgo supercluster. Cluster = A group of galaxies. Supercluster = group of clusters.
the Virgo Cluster is a cluster of galaxies at a distance of approximately 59 million light years
No, a globular cluster is a group of stars that are part of a galaxy. The Virgo cluster is much bigger. It is a large nearby group of galaxies.
the Virgo cluster of galaxies is about 60 million light years away from the Sun.
The nearest cluster of galaxies is the "Virgo Cluster" discovered by Charles Messier in 1784. The Virgo cluster lies at/near the center of the Supercluster we belong to - also called the "Virgo Supercluster". Our "Local Group" (comprising of The Milky way, Andromeda, and another 25-30 smaller galaxies) is part of the Virgo Cluster. The center of the Virgo cluster is at a distance of about 18 Mpc (Mega parsecs) approx 60 Million lightyears from us [which translates to a 'redshift' of only z=0.004]. Ain't the universe huge? Note: There are quite a few 'groups of galaxies' between us and the center of Virgo Cluster.
The Milky Way is part of the Local Group Cluster, part of the Virgo Super Cluster.

The Virgo Super Cluster
The Milky Way is part of the Virgo Supercluster.
No, The Local Group is not. The local group is just an small cluster of a few galaxies on the outskirts of the Local Super-cluster which the Virgo cluster is in the center of it.
Our local cluster is known as - well "The Local Cluster", Not very imaginative I know. It is part of the the Virgo Supercluster or Local Supercluster.
