What are the 3 galaxies in the Local Group?
Bottom line: The Local Group of galaxies consists of three large galaxies – the Andromeda Galaxy (biggest), our Milky Way (2nd-biggest) and the Triangulum Galaxy (3rd biggest) – along with 50 or so much-smaller dwarf galaxies.
How many galaxies are there in Local Group?
The exact number of galaxies in the Local Group is unknown as some are occluded by the Milky Way; however, at least 80 members are known, most of which are dwarf galaxies….
| Local Group | |

What is the local group of galaxies called?
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 most common type of galaxy in the Local Group?
dwarf galaxies
The Milky Way’s more famous satellites are the Large and Small Magellanic Clouds, but there are also around 20 dwarf galaxies orbiting around us. Looking at our Local Group, it’s not hard to understand why astronomers believe that dwarf galaxies are the most common type of galaxy in the universe.
What are the 3 closest galaxies to the Milky Way?
Closest galaxies
| Rank | Galaxy | Distance |
|---|---|---|
| 1 | Milky Way Galaxy | 0 |
| 2 | Canis Major Dwarf | 0.025 Mly |
| 3 | Virgo Stellar Stream | 0.030 Mly |
| 4 | Sagittarius Dwarf Elliptical Galaxy | 0.081 Mly |
How many galaxies make up 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.
What is the nearest galaxy to our own?
Canis Major Dwarf Galaxy
Distance Information The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
Is Andromeda the nearest galaxy?
Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours.
What kind of galaxy do we live in quizlet?
It’s sometimes called the Local Supercluster. It is thought to contain over 47,000 galaxies. galaxy in which we live is shaped like a flat pinwheel, this type of galaxy is a barred spiral galaxy. Our solar system is located in the Orion Arm of this barred spiral galaxy.
Why is it called dark matter?
To account for this, the mass of the galaxy within the orbit of the stars must increase linearly with the distance of the stars from the galaxy’s centre. However, no light is seen from this inner mass—hence the name “dark matter.”
How far is the nearest black hole?
1,000 light-years away
In 2020, a team of astronomers with the European Southern Observatory (ESO) discovered the closest black hole to Earth in the HR 6819 system, just 1,000 light-years away, only to have other scientists dispute the findings.
