One can not realistically measure the size of a galaxy in terms of the size of the Earth.

One usually measures the size of a galaxy in terms of light years.

The solar system of which the Earth is just a small speck sits in our local galaxy, the Milky Way which is 100,000 to 120,000 light years across, while the Andromeda galaxy is slightly larger at 220,000 light years in diameter.

How far is Andromeda galaxy from the Sun?

About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.


Is Andromeda galaxy the biggest galaxy?

Although the Andromeda Galaxy is a bit larger than the Milky Way, and is large as spiral galaxies go, it is not the largest galaxy. There are larger spiral galaxies, and much, MUCH larger elliptical galaxies. However, because it is relatively close to the Milky Way, the Andromeda Galaxy _appears_ quite large, spanning an apparent width roughly six times that of a full Moon. Still, there are two smaller, closer galaxies (the Magellanic Clouds) which appear larger still. (The Magellanic Clouds are not visible from northern latitudes, however, so one could argue that the Andromeda Galaxy is the biggest galaxy in _apparent size_ visible from most of the northern hemisphere.)


Is the Andromeda Galaxy Bigger Than A Universe?

No, the Andromeda Galaxy is not bigger than the universe. The universe is vast and contains billions of galaxies, including the Andromeda Galaxy. The universe is much larger in scale and encompasses everything that exists.


What shape is the Andromeda galaxy?

The Andromeda Galaxy is spiral shaped, much like our own Milky Way Galaxy.See related link for a pictorial.


Are there planets in the Andromeda Galaxy?

It is extremely likely, but we cannot yet find planets from that far away. All the planets we have found to date are in our own galaxy. The Andromeda galaxy is 2.5 million light years away whereas our galaxy is about 100,000 light years across.


How many other small galaxies are there in the Andromeda galaxy?

There are at least 27 known dwarf galaxies orbiting the Andromeda galaxy. These small galaxies are gravitationally bound to Andromeda and are much smaller in size and mass compared to the main galaxy.


How did Edwin Hubble's discovery that the Andromeda galaxy was far away of our own galaxy contribute to astronomers' knowledge about the size of the universe?

Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.


What is bigger the sun or the Andromeda galaxy?

Lmao, 220,000ly gaalxy vs. a dwarf star that has a diameter of 1.3mln km lmao it's obvious Andromeda is a bigger


If we could see unaided the entire disk of the Andromeda Galaxy with the same brightness as its center would the moon be large enough to totally eclipse it?

No. The dimensions of the Andromeda Galaxy are about 190 minutes x 60 minutes (3 degrees+10 minutes x 1 degree) , which is far larger than the Moon's apparent size of 30 minutes (1/2 degree)


What do galaxy mean in this sentence sometimes you can see the Andromeda Galaxy without a telescope?

Our solar system is part of the much larger Milky Way galaxy. Every star, in fact every thing - with one exception - that we see in the night sky is part of our Milky Way galaxy (I am including the large and small Magellanic clouds, because they are gravitational sattelites of our galaxy). The one exception is another galaxy - two and a half million light years away - that can just barely be seen with the naked eye on clear nights. We call that galaxy Andromeda, as we see it in the direction of the constellation Andromeda. There are believed to be billions of galaxies, but Andromeda is the one closest to us.


Is the Andromeda galaxy in the Northern Hemisphere?

The Andromeda Galaxy can be seen from the northern hemisphere. Above the 45th parallel it is circumpolar, meaning you can see it pretty much any time of the night. If you know where Cassiopeia is, the Andromeda Galaxy is a fuzzy patch of light visible to the naked eye (on really dark nights) between that asterism (the Flying W) and the constellation of Andromeda. The five bright stars that make up Cassiopeia--Andromeda is below the W. The rim stars are dim, even through a good 14" telescope you can generally only make out the core stars. Otherwise the galaxy would appear a bit larger than our own moon, from our perspective here on earth. Andromeda is 2.5 million light years away, and a bit bigger than our galaxy.


Will the Milky Way and Andromeda galaxy dash each other?

If the Milky way and Andromeda does in fact collide (the accuracy of the prediction is not accurate enough to confirm certainty), then we can expect one of two outcomes.Andromeda envelopes our galaxy and together they form a much larger elliptical galaxy.They pass right past each other, with the gravity of Andromeda "stealing" part of our galaxy which would lead to our solar system being ejected from the Milky way or forming part of Andromeda. (by that time our Sun would have, or could have gone Red Giant already)
