Q: What is the Closest Galaxy to ours?

A fellow here in the computer lab is askin and I thought of all the
folk I converse with _this_ group would have a ready answer.

Of course I'll be Googeling right afterI post this but its often
wheatberries amoungst the chaff time with the search engine.

In any case Thx in advance.

M31 aka Andromeda .. unless you count the Magellanic Clouds.

Gee .. hope I got this right

Also from http://www.seds.org/messier/more/local.html looks
like CMa dw galaxy is the closest at 25,000 light years.

Below we list some nearby but probably non-member field galaxies (which are also not members of one of the neighboring
groups listed above), in the same format as above:

There's the small ones that are in orbit around our galaxy, LMC/SMC/Sag.Df.
galaxy, outside of them and coming at us is M31.

Hmm, it looks like (for a long time) Andromeda was the goto answer.

Now I'm finding out about a Dwarf Galaxy we (the milky Way) are
cannibalizing, it seems to be in/ part of Canis Major.

Well, Thx everybody.

TBerk -

Just to add another reference -

Powell's Atlas of the Universe
Local Galaxy Groups Map
http://anzwers.org/free/universe/localgr.html
Local Galaxy Groups Table
http://anzwers.org/free/universe/galaxies.html

This excludes the partially cannibalized and graviationally captured
dwarf galaxies mentioned in other posts in this thread.

I typically assign those objects to the "Milky Way System" as opposed
to the "Local Group" of galaxies.

Powell's Atlas of the Universe
The Satellite Galaxies [of the Milky Way]
http://anzwers.org/free/universe/sattelit.html

The picture in Powell's Atlas does not show the Canis Major Dwarf
galaxy which is basically inside the Milky Way spiral arm structure and
which is shown in the APOD picture posted by St. John Smythe in this
thread.
http://antwrp.gsfc.nasa.gov/apod/ap031117.html

So, a fair answer to the top poster's question depends on how you
define a "galaxy" and how you define what is the "Milky Way Galaxy."
If you mean a dwarf galaxy and the "Milky Way" means only the spiral
arm structure and Milky Way core - it's the Canius Major Dwarf at 12
kiloparsecs. If you mean, what lay people would call a "real galaxy"
and the "Milky Way system," it's either Andromeda at about 735
kiloparsecs or a small dwarf outside the Milky Way System, like Leo II
at 205 kiloparsecs.

But IMHO you can fairly look at the answer both ways.
