You have already answered your own question. The Local Group of galaxies are not very close, but close enough to be gravitationally held together in a group. The biggest galaxies in the Local Group are ours (The Milky Way)and the Andromeda Galaxy (M31). They are being pulled together and will eventually collide.
thank you so much:-)
