Yes.The only ones I know is IC 1101 and Messier 87.The Andromeda galaxy is twice the size of our Milky Way.The Andromeda is 260,000 light years across,while the Milky Way is 100,000 light years across.A light year is 5,878,499,812,499 miles.
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.
It's difficult to define a galaxies size, as there is no real cut off point. From estimations, the Andromeda is about twice as large as the Milky Way.
About twice the size of the Milky Way, so about 200,000 light-years across, so the Milky Way is 100,000 light-years across.

I believe it's a size thing.
The nearest large galaxy to the Milky Way is the Andromeda Galaxy. It is of similar size and is visible in dark skies.
Under the correct conditions it may be possible to see the Andromeda Galaxy. Although, it does appear very feint in the night sky, it would appear roughly twice the size of the Moon if it were bright enough to be seen edge-to-edge. Its central bulge could be viewed if using a telescope or a good pair of binoculars.
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.

It is unknown for sure but by the way it looks, the Andromeda galaxy is the largest. The Ansromeda galaxy is the closest galaxy to the Milky Way and is about three times the size of the Milky Way.
It's difficult to define a galaxies size, as there is no real cut off point. From estimations, the Andromeda is about twice as large as the Milky Way.
The Milky Way galaxy will collide with Andromeda, but it will take about a 2 billion years until they collide and finish. Earth will not get blown up, but by then, the sun will probably be out of hydrogen and expand. Then earth will be engulfed and all life will die.
They are pretty similiar mass, Milky Way maybe has more mass, but the Milky Way indeed beats it in size. Milky Way is 258,000ly in diameter. Andromeda is 220,000 ly, Andromeda and the Milky Way are like twins.
About twice the size of the Milky Way, so about 200,000 light-years across, so the Milky Way is 100,000 light-years across.
