NGC 5364is agrand design spiral galaxylocated 54.5[2]millionlight yearsaway in theconstellationVirgo.It isinclinedto theline of sightfrom the Earth at an angle of 47° along aposition angleof 25°.[7]It is a member of theNGC 5364 Groupof galaxies, itself one of theVirgo III Groupsstrung out to the east of theVirgo Superclusterof galaxies.[8]

Themorphological classificationof NGC 5364 in theDe Vaucouleurssystem is SA(rs)bc pec,[4]which indicates it has an incomplete ring structure (rs) in the inner part of the galaxy with moderate to loosely wound arms (bc) and has a peculiar aspect (pec).[5]In particular, the appearance of the spiral arms is amorphous and asymmetrical compared to other galaxies with a similar classification.[4]A companion galaxy,NGC 5363,is located to the north of NGC 5364 and their gravitational interaction may be influencing the peculiar morphology of the latter.[2]
The mid-infrared emission in the nucleus appears weak compared to the spiral arms, suggesting a low rate of star formation in the core region.[4]The inner ring of this galaxy spans a diameter of 22 kly (6.7 kpc) and is located slightly off center with the northern side showing a stronger emission in thehydrogen alphaband compared to the southern half. MultipleH II regionslie along the spiral arms, tracing out their extent.[2]Each of the two main arms wrap all the way around the galaxy, although they display patchiness along much of their length.[5]
NGC designation[edit]
This object was discovered byWilliam Herschelon February 2, 1786, and later listed as NGC 5364. It was subsequently rediscovered byJohn Herschelon April 7, 1828, and later listed as NGC 5317.[9]
