NGC 5360 = IC 958 ist eine linsenförmige Galaxie vom Hubble-Typ SB0/a im Sternbild Jungfrau auf der Ekliptik. Sie ist schätzungsweise 51 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 25.000 Lj.
Im selben Himmelsareal befinden sich u. a. die Galaxien NGC 5317, NGC 5348, NGC 5356, NGC 5363.
Das Objekt wurde am 8. Mai 1864 vom deutschen Astronomen Albert Marth entdeckt. Der US-amerikanische Astronom Lewis A. Swift beschrieb, wahrscheinlich ohne das Wissen über die Existenz von NGC 5360, bei einer Beobachtung am 19. April 1890 die Galaxie mit „eeeF, pS, iR; seen only by glimpses“[4], sie wurde damit als IC 958 in den Index-Katalog aufgenommen.[5]

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.
