The Virgo Supercluster (in which the Milky Way is located) is about 200 million light years across.
The Virgo Supercluster, often just called the Local Supercluster
The Local group for the clusterThe Virgo Super Clusters for the Supercluster
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.
Yes it is. A supercluster has up to 50 galaxies where the local group contains up to 30. The local group cluster is actually located within the Local (or Virgo) supercluster.
The cluster, which contains the Milky way and more than 50 other galaxies, is called the Local Cluster. The cluster has a diameter of 3.1 million parsecs (10 million light years). The Local Group is part of the much larger Virgo Supercluster.
The local group has a diameter of about 10 million light years.
The Milky Way is part of the Local Group, which 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.
No, not at all. Jupiter is part of the Solar System, which is part of the Milky Way galaxy, which is part of the Local Group (of Galaxies), which is part of the Local Superclusters. Jupiter's mass is nothing when compared to the mass of Superclusters.
Because light travels at a large but finite velocity, the actual position of celestial objects by the time their light reaches us has advanced in time by the amount of time it look the light to reach us. One way of illustrating this is to consider that the light we see from Andromeda galaxy, which is a distance of 2.5 million light years away (770 Kpc), is actually how the Andromeda used to look like 2.5 million years ago. Since that time it has continued to spin around its central mass, and continued to revolve with the other galaxies around the common center of gravity of the local cluster, and its larger supercluster, etc. If we were able to briefly time-travel into the future and observe it from Earth two and a half million years from now, we'd see where it "actually" is today.
The Milky Way is located in the Local Clusterwhich contains about 30 galaxies. It is on of the biggest of them and it also has a twin galaxy called Andromeda. The local cluster is located a galaxy cloud called Canes Venaticiwhich together with 6 other galaxy clouds makes the Local Supercluster.
A supercluster is a collection of clusters. There is no defined amount of clusters. A cluster could have up to 10 trillion stars, so a supercluster could contain around a quadtrillion stars.
