NGC 5668 is a nearly face-on
NGC 5638 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.[5]
As seen from the Earth, it is inclined by an angle of 18° to the line of sight along a position angle of 145°. The morphological classification in the De Vaucouleurs system is SA(s)d,[2] indicating a pure spiral structure with loosely wound arms.[6] However, optical images of the galaxy indicate the presence of a weak bar structure spanning an angle of 12″ across the nucleus. There is a dwarf galaxy located around 650×103 ly (200 kpc) to the southeast of NGC 5668, and the two may be gravitationally interacting.[2]
Three
neutral hydrogen have been observed in NGC 5668, which may have their origin in supernova explosions and strong stellar winds.[9]
