Hi! I guess I never payed much attention to the sizes of the galaxies in the local group before. When APOD said that the Triangulum was the third largest; I started to investigate. I found out that the LMC was the 4th largest and a lot of the others are dwarfs. We know Andromeda is on a merging course with The Milky Way: then what about the smaller ones that are out there? Could be one very large galaxy someday.
