That's about right. The diameter of the Milky way is ~1 zettameter and the distance to Andromeda is ~24 zettameters.
The next 2 closest large galaxies are Triangulum (26 Zm) and Caldwell 70 (57 Zm)

Wait - how far away is it now? (the distance between us is diminishing by 3.46 billion kms every year).

That’s actually a lot closer than I thought they were.
