Galaxy that does not belong to a larger cluster of galaxies

Afield galaxy is agalaxy that does not belong to a largergalaxy group or cluster and hence isgravitationally alone.

Roughly 80% of all galaxies located within5 Mpc (16 Mly) of theMilky Way are in groups or clusters of galaxies.^[1] Mostlow-surface-brightness galaxies are field galaxies.^[2] Themedian Hubble-type of field galaxies is Sb, a type ofspiral galaxy.^[3]
