NGC 5668 is a nearly face-on spiral galaxy, visual magnitude about 11.5,[4] located about 81[2] million light years away in the constellation Virgo.
The morphological classification in the De Vaucouleurs system is SA(s)d,[2] indicating a pure spiral structure with loosely wound arms.
[7] 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 650×10^3 ly (200 kpc) to the southeast of NGC 5668, and the two may be gravitationally interacting.
[2] Three supernovae have been observed in this galaxy: High velocity clouds of neutral hydrogen have been observed in NGC 5668, which may have their origin in supernova explosions and strong stellar winds.
