The Andromeda Galaxy is about how many light years away from Earth

Andromeda Galaxy, located 2.54 million light-years from Earth, is made up of more than a trillion stars.

The Andromeda Galaxy is a spiral galaxy with a giant **-like structure located in the direction of the constellation Andromeda.

The Messier catalog is numbered M31, with a diameter of 220,000 light-years, and is 2.54 million light-years from Earth, which is the distance from the Milky Way.

The nearest large galaxy. Scientists have measured its distance from the Earth in three ways.

1. Cepheid Variation Method.

In 2004, using the Cepheid method of variable stars, the estimated distance was 2.51 million light trembling grandchildren, which deviated from the value.

at 130,000 light years.

2. Use eclipse double star to calculate.

In 2005, scientists announced the discovery of an eclipse binary star in the Andromeda Galaxy. Scientists used it to calculate that the entire Andromeda constellation is 2.5 million light-years away from Earth. This new data is considered to be much more precise than the previous ranges measured with Cepheids alone.

3. Red Giant Branch Technology.

Scientists measured a distance of 256 light-years using the red giant branching technique, with a deviation of 80,000 light-years.

So, according to the above measurements, the Andromeda Galaxy is on average 2.54 million light-years away from Earth.

The Andromeda Galaxy is a spiral galaxy.

It is made up of more than one trillion stars with roughly twice the mass of a galaxy. In the Northern Hemisphere, where there is no light pollution.

We can observe the Andromeda Galaxy with the naked eye, but the Andromeda Galaxy is dimly lit and looks like a cloud. Qindong bucket.

The diameter of the halo of Andromeda is more than two million light years, it is a halo composed of a large amount of gas, this halo is very thin, but it can spread to a long distance, and the Milky Way itself also has a halo, if you count the coverage of the halo, it means that it and the Milky Way have met.

Of course, the main structures of the two galaxies are still separate, and they will not merge together until 100 million years later. After the impact, they will regroup, and the starry sky on Earth will inevitably change, and a large number of stars will be born.

It is about 300 light-years away from Earth. According to current scientists, the source of the Hail Andromeda source galaxy is 300 light-years away from Earth, so far away is composed of some gas and floating rock.

The Andromeda Galaxy is a spiral galaxy located in the direction of the constellation Andromeda with a giant ** noisy structure, the Messier catalog number is M31, its diameter reaches 220,000 light years, and it is 2.54 million light years away from the Earth, which is the closest large galaxy to the Milky Way. The diameter of the halo of Andromeda is more than two million light years, it is a halo composed of a large amount of gas, this halo is very thin, but it can spread to a long distance, and the Milky Way Songbona system itself also has a halo, if you count the coverage of the halo, it means that it and the galaxy have met.

It is 2.2 million light-years away from Earth, and it is very far from Earth. It is mainly composed of Andromeda Antario and Andromeda Kuishou Morning Su, which is what I have learned.

It is more than 2 million light-years away and consists of 1 trillion red stars. The Andromeda Galaxy is lovely.

There is no such thing as "how far a constellation is from Earth". Constellations are actually patterns of different bright stars connected by their positions being projections on the celestial sphere. The bright stars that make up these constellations are actually far apart, but they form a pattern in similar directions on Earth, that is, constellations - so it cannot be said how far a constellation is from the Earth.

The Andromeda Galaxy (M31), also known as the Andromeda Nebula, is located about 2.2 million light-years from Earth and is a major member of the Milky Way Group. But Andromeda and the Andromeda Galaxy are two different concepts. For the constellation Andromeda, it is mainly composed of bright stars in the picture, which are within 200 light-years of the Earth

6. Andromeda is a galaxy that can't be said how far away.

You probably mean how far away the Andromeda Nebula is. The Andromeda Galaxy is the closest large galaxy to our own galaxy, the diameter of the Andromeda Galaxy is 50 thousand parsecs (160,000 light years), double the diameter of the Milky Way, and it is the largest galaxy in this group of galaxies, about 2.2 million light years away...2, 22.2 million light years, 1, Andromeda Galaxy.

The Andromeda Galaxy (M31), also known as the Andromeda Nebula, is located about 2.2 million light-years from Earth and is a major member of the Milky Way Group. With a diameter of 160,000 light-years, a mass of no less than the power of the power of the solar mass, and more than 250 billion stars, it is the largest of the group.

We see the constellation Andromeda 2.2 million years ago (the galaxy is light years away from us, and we see the galaxy from a few years ago)...1,

2.54 million light years.

Andromedagalaxy (Andromedagalaxy; m31;ngc224；Once known as the Great Andromeda Nebula), a spiral galaxy with a giant **-like structure located in the direction of Andromeda, the Messier catalog number is M31, and the new general catalog number of the nebula cluster is NGC224, with a diameter of 220,000 light years and a distance of 2.54 million light years from Earth.

The Andromeda Galaxy, which appears as a spindle-shaped elliptical spot in the northeast sky, is one of the most distant objects visible to the naked eye to Liang Chang. The Andromeda Galaxy is generally considered to be the largest galaxy in the local group of galaxies, similar in appearance to the Milky Way. The members of this group of galaxies include the Andromeda Galaxy, the Milky Way, the Triangulum Galaxy, and about 50 smaller galaxies.

Fruit is produced based on improved measurement techniques and data from recent studies.

The true distance between the Fairy Bureau and the Immortal Earth is () 10,000 light-years.

Correct Answer: Crack B

A light year is one of the units of length, which refers to the distance traveled by light in a vacuum in a year, a total of 365 * 24 * 60 * 60 seconds in a year, then 1 light year = 365 * 24 * 60 * 60 * 3 * 10 to the eighth power of the meter. The distance between them is 200 W light years, so use 200 W to multiply the distance by 1 light year, which is the answer. The answer sought is 18,921,600,000,000,000,000,000,000 meters (i.e. 22 to the power of meters).

2000000*365*3600*24*3*10 8 so many meters.

That's the distance traveled by light in 2 million years.

3. The problem of our human eyeballs. The last point is to return to us as human beings. Although we humans are the most intelligent animals in the whole natural world, there are also parts of our bodies that are not fully evolved, such as our eyes, which are far less resolution than other animals, so you can't see some distant objects a lot of the time, and that's exactly why.

The Andromeda Galaxy is only 2.2 million light-years away, but because the Andromeda Galaxy is constantly moving, it is the size of a star to our human eyes.

The main reason for this is because the Andromeda galaxy has gone far beyond what we can observe. So at such a distance, we can only see a galaxy as a star.

Because it's so far away from us, 2.2 million light-years is already far, far away, and it's good that we can see it.
