 SUWT2, the central star, is actually a close binary system where two stars completely circle each other every five days. The interaction of these stars and the more massive star that sheds material to create the nebula formed the ring structure. The burned-out core of the massive companion has yet to be found inside the nebula. This nebula is dubbed the starfish because of its shape, the six lobes of gas and dust, which resemble the legs of a starfish, suggest that the nebula puffed off material at least three times in three different directions. NGC 5315 is a chaotic-looking nebula and reveals an X-shaped structure.
