NGC 4605 is a dwarf barred spiral galaxy [6] in the constellation Ursa Major, located at a distance of 18.1 ± 0.3 megalight-years from the Milky Way. [5] Physically it is similar in size and in B-band absolute magnitude to the Large Magellanic Cloud. [6] It is a member of the M81 Galaxy Group, along with Messier 81 and Messier 101. [9]
