I think it is very difficult to define size to a galaxy, as there is not real cut off point. Recent observations showed a "halo" of Stars around the Galaxy - a bit like suburbs to a city. Putting the size to 500,000 light years across. Current thoughts are that it is twice the size of our own Galaxy, so around 200,000 light years across.
Maybe someone else can contribute a more recent guesstimate.
Earth, Sun, Andromeda galaxy and then the universe. increasing size------------------------->
No scale was specified. However, if the Earth was one inch, the Andromeda Galaxy would be 29,300,000,000 miles away.
Because the Andromeda Galaxy or M31 is a major galaxy and is found in the constellation Andromeda.
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.
The Andromeda Galaxy was created in 1992.

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.
Yes, the Andromeda Galaxy is a spiral.
The ISBN of The Andromeda Galaxy is 0792316541.

Andromeda is a spiral galaxy, similar to our own.
M31 in Andromeda is a classic spiral galaxy.
