NGC 4088 = Arp 18 is a barred spiral galaxy of the Hubble type SBbc in the constellation Great Bear in the northern sky . It is estimated to be 37 million light years from the Milky Way and about 60,000 light years in diameter. The galaxy shows noticeable deformations of the spiral arms , possibly caused by NGC 4085, which is located at a similar distance .
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class spiral galaxies with separated sections (Arp catalog) .
The supernovae SN 1991G (Type IIP) and SN 2009dd (Type II) were observed here.
The object was discovered by Wilhelm Herschel on March 9, 1788 .
