NGC 5364

NGC 5364 is a grand design spiral galaxy located 54.5[3] million light years away in the constellation Virgo.

[9] The morphological classification of NGC 5364 in the De Vaucouleurs system 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.

[3] 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 the hydrogen alpha band compared to the southern half.

Sometimes called a "grand design", spiral galaxy, it is characterised by their prominent, well-defined arms, which circle outwards from a clear core ( HST -image)
