What is considered the Local Group?
The Local Group is the galaxy group that includes the Milky Way. It consists of two collections of galaxies in a “dumbbell” shape: the Milky Way and its satellites form one lobe, and the Andromeda Galaxy and its satellites constitute the other.
What is the Local Group quizlet?
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. very large spherical region that surrounds the Milky Way.
What is the Local Group orbiting?
The Local Group, in turn, is part of the Virgo Supercluster, which spans just over 100 million light-years and is thought to contain at least 100 galaxy groups and clusters. They say it’s the most detailed map ever of the orbits of galaxies in our extended local neighborhood.
How many local groups are there?
There are over 30 galaxies that are considered to be in the local group, and they are spread over a diameter of nearly 10 million light years, with the center of them being somewhere between the Milky Way and M31. M31 and the Milky Way are the most massive members of the Local Group, with M33 being the 3rd largest.

How many galaxies are in the Local Group quizlet?
How many galaxies are in our local group? 40.
Which is the largest galaxy in our Local Group?
The Milky Way galaxy
The Milky Way galaxy is one of more than 54 galaxies known as the Local Group. The three largest members of the group are our Milky Way (second-biggest), the Andromeda galaxy (biggest) and the Triangulum Galaxy.
What are 4 types of galaxies?
In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies.
What are the members of the local group?
We know where our galaxy is located, but only locally speaking. The Milky Way galaxy is one of more than 54 galaxies known as the Local Group. The three largest members of the group are our Milky Way (second-biggest), the Andromeda galaxy (biggest) and the Triangulum Galaxy.
What is the name of the local group of galaxies?
Group of galaxies that includes the Milky Way. Local Group of galaxies, including the massive members Messier 31 (Andromeda Galaxy) and Milky Way, as well as other nearby galaxies. Distribution of the iron content (in logarithmic scale) in four dwarf neighbouring galaxies of the Milky Way.
Is the Milky Way part of the local group?
Both M31 and the Milky Way have dwarf galaxies associated with them. The dynamics of the Local Group are changing, and some astronomers speculated that one day the two large spirals in it (M31 and the Milky Way) may collide and merge to form a giant elliptical galaxy.
Where is the center of the local group?
Local Group. Its gravitational center is located somewhere between the Milky Way and the Andromeda Galaxy. The Local Group has a diameter of 10 Mly (3.1 Mpc) (about 10 23 meters) and has a binary (dumbbell) distribution. The group itself is a part of the larger Virgo Supercluster, which may be a part of the Laniakea Supercluster .
