NGC 5247 is a face-on unbarred spiral galaxy located some 60[3] million light years away in the constellation Virgo. It most likely belongs to the Virgo Supercluster of galaxies; the same supercluster that hosts the Milky Way galaxy. This is a grand design spiral galaxy that displays no indications of distortion caused by interaction with other galaxies.[4] It has two spiral arms that bifurcate after wrapping halfway around the nucleus.[5] 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.[4]
