NGC 1087
Encyclopedia
NGC 1087 is an intermediate spiral galaxy
in Cetus. The central bar/core is very small with many irregular features in the surrounding disk of material. With the many strange features of NGC 1087, its true nature is still uncertain. It has an extremely small nucleus and a very short stellar bar. Unlike most barred galaxies, the bar apparently has some new star-formation taking place. There is a multiple spiral structure defined more by the dust lanes than by luminous matter. Overall, the disc has a very low surface brightness. Even though it appears close to another galaxy (NGC 1090
), these two galaxies are not interacting and should be considered isolated from one another.
NCG 1087 lies near the small M77 (NGC 1068)
galaxy group that also includes NGC 936, NGC 1055
, and NGC 1090
. However, because of its distance, it probably is not an actual group member.
Based on the published red shift
, (Hubble Constant of 62 km/s per Mpc) a rough distance estimate for NGC 1087 is 80 million light-years, with a diameter of about 86,800 light-years.
Intermediate spiral galaxy
An intermediate spiral galaxy is a galaxy that is in between the classifications of a barred spiral galaxy and an unbarred spiral galaxy. It is designated as SAB in the galaxy morphological classification scheme.-Grades:...

NGC 1055
NGC 1055 is an edge-on spiral galaxy located in the constellation Cetus that has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas. The spiral arm structure appears to be elevated above the galaxy's plane and obscures the upper half of the bulge...
