What is meant by the Local Group?
Local Group, in astronomy, the group of more than 20 galaxies to which the Milky Way Galaxy belongs. About half are elliptical galaxies, with the remainder being of the spiral or irregular type. As in other clusters of galaxies, members are probably kept from separating by their mutual gravitational attraction.
What is the Local Group part of?
the Virgo Supercluster
It’s somewhere between the Milky Way and the Andromeda Galaxy. Astronomers have also discovered that our Local Group is on the outskirts of a giant supercluster of galaxies, known as the Virgo Supercluster.
What does the Local Group orbit?
Most of the light (and mass) in the Local Group is contained in the two large spiral galaxies, the Milky Way and Andromeda, and most of the known smaller members of the Local Group are satellite galaxies orbiting these systems.
What are some members of the Local Group?
One of the most prominent members of the Local group is M31, the Andromeda Galaxy. It has two small satellite galaxies, M32 and M110. Also prominent in the local group is the Triangulum Galaxy (M33), Leo I, and NGC 6822.
What is the Local Group quizlet?
What is the Local Group? The Local Group is the galaxy group that includes the Milky Way. The Local Group comprises more than 54 galaxies, most of them dwarf galaxies. Its gravitational center is located somewhere between the Milky Way and the Andromeda Galaxy.
Can we escape the Local Group?
The rate of expansion is set to increase with time as the universe expands. It may still be possible to escape the Local Group, but there will be some limit to the distance we could travel and be able to reach another galaxy.
What is the Local Group NASA?
The Local Group (also called M31 group or the Andromeda group) is the group of galaxies that includes our galaxy, the Milky Way.
What is the relationship of the Milky Way to the Local Group?
The Local Group is the galaxy group that includes the Milky Way. It has a total diameter of roughly 3 megaparsecs (10 million light-years; 9×1022 metres), and a total mass of the order of 2×1012 solar masses (4×1042 kg).
What Local Group of galaxies is the Milky Way part of quizlet?
The Milky Way is a part of the Local Group cluster which contains more than 50 other galaxies.

What is the relationship between Milky Way and Local Group?
Is the Local Group One of the largest clusters known?
Local Group The cluster of galaxies of which our Galaxy is a member. It is a comparatively small cluster with around 40 known members and some other possible members, most of which are dwarf ellipticals or irregular galaxies (see table). The most massive members are the Galaxy and the Andromeda galaxy (M31).
What holds the local group together?
The Local Group members are bound together by their mutual gravitational attraction and they stick together quite well. Most galaxies in the universe are accelerating away from us, driven by the action of dark energy , but the Milky Way and the rest of the Local Group “family” are close enough together that they stick together through the force
