NGC 4395 is a nearby low surface brightness spiral galaxy located about 14 million light-years (or 4.3 Mpc) from Earth in the constellation Canes Venatici.

[1] The nucleus of NGC 4395 is active and the galaxy is classified as a Seyfert Type I known for its very low-mass supermassive black hole.

Along with several other nearby galaxies, resolved stars in NGC 4395 were used to measure the expansion rate of the Universe by Allan Sandage and Gustav Andreas Tammann in their 1974 paper.

[7] Since then, its nucleus has been the subject of several academic papers and attempts to measure the mass of its central black hole.

[4] The nucleus of NGC 4395 is notable for containing one of the smallest supermassive black holes with a well-measured mass.
