NGC 5364 = NGC 5317 ist eine Spiralgalaxie vom Hubble-Typ Sbc/P und liegt im Sternbild Virgo am Nordsternhimmel. Sie ist rund 54 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 105.000 Lichtjahren. Das Objekt hat mit NGC 5363 eine Begleitgalaxie, deren gravitativen Kräfte für die ausgedehnten Sternbildungs-Regionen in den Spiralarmen verantwortlich ist.
Entdeckt wurde die Galaxie am 2. Februar 1786 von William Herschel (als NGC 5364 aufgeführt). „Wiederentdeckt“ am 7. April 1828 von John Herschel (als NGC 5317 gelistet).[4]

With its swirling arms and luminous core, NGC 5364 is unmistakably a spiral galaxy, lying in the constellation Virgo. But it’s not just any spiral galaxy imaged by the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab. This eye-catching stellar body is classified as a grand design spiral galaxy. Grand design spiral galaxies are characterized by prominent, well-defined arms that circle outwards from a distinct core. Only ten percent of spiral galaxies are given this descriptive name and they are considered the archetype of spiral galaxies owing to their ‘perfect’ structure. However, NGC 5364 is not as perfect as it may appear. Compared to other grand design spirals, its arms are actually amorphous and asymmetrical. This distortion is thought to be due to interactions with the nearby lenticular galaxy NGC 5363, which can be seen in this image as a fuzzy smear below NGC 5364. Despite its significantly smaller size, the close proximity of this galaxy to NGC 5364 results in a mutual tugging. This moves around the stars and gas within NGC 5364’s arms and warps the overall shape of the galaxy.

This eye-catching galaxy is known as NGC 5364.
Unmistakably a spiral, NGC 5364 is also something known as a grand design spiral galaxy — a descriptive name deserved by only one-tenth of spirals. While all spirals have a structure that is broadly similar, there is quite a bit of variation amongst individual galaxies; some have patchy, oddly-shaped arms, some have bars of stars cutting through their core, some are colossal and radiant, and others are dim and diminutive. Grand designs like NGC 5364 are in many ways the archetype of a spiral galaxy. They are characterised by their prominent, well-defined arms, which circle outwards from a clear core.
Despite being classified in this way, NGC 5364 is far from perfect. Its arms are asymmetrical compared to other grand design spirals — this is thought to be due to interactions with a nearby neighbour. This neighbour and NGC 5364 are tugging on one another, warping and moving their stars and gas around and causing this misshapen appearance.
