Field galaxy

A field galaxy is a galaxy that does not belong to a larger cluster of galaxies and hence is gravitationally alone.

Roughly 80% of all galaxies located within 5 Mpc (16 Mly) of the Milky Way in groups or clusters of galaxies.^[1] Most low-surface-brightness galaxies are field galaxies.^[2] The median Hubble-type of field galaxies is Sb, a type of spiral galaxy.^[3]
