NGC4605 is a peculiarly shaped barred spiral galaxy seen in the northern part of Ursa Major, located 5.6 degrees northeast of δ Ursae Majoris, one of the stars forming the Big Dipper.
It has a cigar-like appearance with a major-axis length of 5.7 arcminutes, and no well-defined spiral structure is visible.
Although faint, asymmetric dust lanes can be seen distributed within the galaxy.
It lies at a distance of about 18 million light-years and, despite being separated by as much as 18 degrees on the sky, is thought to belong to the same galaxy group as M81 and M82 in Ursa Major.
