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. It was discovered on 29 April 1786 by William Herschel. [4]

Contents

NGC 5668 is a member of the NGC 5638 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies. [5] In addition, A.M. Garcia listed NGC 5668 in the 31 member NGC 5746 galaxy group (also known as LGG 386). [6]

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. [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]

Supernovae

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. [15]
