    How does one telephone differ from another? One car from another? It's the same kind of thing, if I'm not mistaken.

    They differ in almost every aspect possible.

    Is there a way to measure how big or small a galaxy is compared to ours? What is the smallest galaxy we know of?

    With the caveat that there is still a little debate about it, using doppler shift to find distance (there are other ways for closer galaxies) and measuring the angular size will give the actual size.
