NGC 5907 is an edge- to- edge spiral galaxy in the constellation of Dragon with an apparent magnitude of 10.4 mag. It can be found 2.9 ° south-southwest of the 3.3 mag bright star ι Draconis and about 1 ° north of the two 11.7 and 11.8 mag bright spiral galaxies NGC 5905 and NGC 5908 in the vicinity of the Bear Guardian constellation . NGC 5907 is 12.6 '× 1.4' in size with almost no visible bulge . The galaxy is therefore very slim and presumably of the Hubble type Sc. NGC 5907 is likely a member of the galaxy group around NGC 5866, about 40 million light years from Earth . According to this distance and its angular extent, it has a diameter of approximately 150,000 light years.
The galaxy was discovered on May 5, 1788 by the German-British astronomer Wilhelm Herschel . Your occasionally used English name Splinter Galaxy was coined in 1970 by the amateur astronomer Walter Scott Huston. The galaxy's faint glow on the west side of its disk's dark band of dust was discovered on April 13, 1850 by George Johnstone Stoney , an assistant to Lord Rosse , and is recorded as NGC 5906 .
