NGC 5247 is a face-on unbarred spiral galaxy located some 60 [3] million light years away in the constellation Virgo. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. [4] This is a grand design spiral galaxy that displays no indications of distortion caused by interaction with other galaxies. [5] It has two spiral arms that bifurcate after wrapping halfway around the nucleus. [6] The disk is estimated to be 4.9 ± 2.0 kly (1.5 ± 0.6 kpc) in thickness and it is inclined by roughly 28° to the line of sight. [5]
