NGC 3985 is a barred spiral galaxy in the constellation Ursa Major. It is located at a distance of about 45 million light years from Earth, which, given its apparent dimensions, means that NGC 3726 is about 18,000 light years across.[1] NGC 3985 is situated north of the celestial equator and, as such, it is more easily visible from the Northern Hemisphere.[2] The galaxy appears to have one spiral arm.[3]
