NGC 4088 is an intermediate spiral galaxy in the constellation Ursa Major. The galaxy forms a physical pair with NGC 4085, which is located 11′ away.[4]
NGC 4088 is a grand design spiral galaxy.[5] This means that the spiral arms in the galaxy's disk are sharply defined. In visible light, one of the spiral arms appears to have a disconnected segment. Halton Arp included this galaxy in the Atlas of Peculiar Galaxies as one of several examples where this phenomenon occurs.[6]
NGC 4088 and NGC 4085 are members of the M109 Group, a group of galaxies located in the constellation Ursa Major. This large group contains between 41 and 58 galaxies, including the spiral galaxy M109.[7][8][9]
On April 13, 2009, SN 2009dd was discovered in NGC 4088.[10]Atapparent magnitude 13.8,[10] it became the third-brightest supernova of 2009.[11] In 1991 there was SN1991G.
