Discovered 1788 by William Herschel.
Besides M102 candidate NGC 5866, this is the second prominent member of the NGC 5866 group. As it is seen almost exactly edge-on, and is an extremely flat disc, it appears extremely elongated, shaped like a "knife edge" or a splinter, therefore its popular name.
William Herschel discovered this galaxy together with NGC 5866 and several fainter galaxies in this celestial area on May 5, 1788, and cataloged it as H II.759.
Supernova 1940A, which was discovered by Johnson, occurred in NGC 5907 on February 16, 1940 and reached magnitude 14.3 (see PASP 52, 146).

According to Michael Ferrio, the name Splinter Galaxy occurred in the Deep-Sky Wonders column. The small distinct part of the galaxy has the extra NGC number 5906.
