10-12 billion years old.
Yes its called the Local Cluster or Local Group, we have many minor Globular or Cluster Galaxies orbiting our own.
In our Milky Way galaxy, globular clusters tend to be at the "outlying fringes" or "halo" of the galaxy, and seem to be largely made up of very old stars.
Planet earth is not in any of the approximately 150 globular clusters which are known to exist in our galaxy, the Milky Way. Our solar system is on one of the spiral arms of the Milky Way.
The Milky Way is part of the Local Group Cluster, part of the Virgo Super Cluster.
No, the Milky Way is a galaxy
The cluster that contains a group of older stars located in the halo of the Milky Way is known as a globular cluster. These clusters are tightly bound together by gravity and typically contain stars that are very old, often several billion years. An example of a well-known globular cluster is M13, also known as the Hercules Cluster, which is situated in the constellation Hercules. Globular clusters are important for studying the early history of the galaxy and the formation of stars.
the halo
Earth belongs to the Milky Way galaxy, which contains numerous star clusters. Specifically, our solar system is located in the Orion Arm of the Milky Way, but it is not part of a distinct star cluster. Instead, it is part of the larger structure of stars within the galaxy. The Milky Way itself is a barred spiral galaxy with various clusters, including globular clusters and open clusters.
Globular clusters are small groups of stars, while the milky way is a large galaxy containing hundreds of billions of stars, along with some of these clusters.
A cluster of stars that looks like a ball and contains up to 1 million stars is called a globular cluster. These clusters are densely packed groups of stars bound together by gravity and can be found in the halos of galaxies.
Viewed from the Galactic North Pole, the Milky Way galaxy is moving anticlockwise.
