NGC 5907 is a spiral galaxy in Draco. Seen nearly edge-on and almost perfectly bisected by its dust lane, it resembles NGC 4565, but with an important difference. NGC 5907 is a class Sc spiral, with a much smaller central bulge than a class Sb spiral, like NGC 4565, giving it a needle-like profile. Because of this distinctive profile, NGC 5907 is known as the Needle Galaxy or Splinter Galaxy. NGC 5907 lies approximately 50 million light-years from Earth. The small blue spiral galaxy to the lower left of NGC 5907 is KUG1513+566.
