Encyclopedic overview
NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. Near NGC 3718 is the galaxy NGC 3729, a peculiar barred spiral galaxy. It is either a lenticular or spiral galaxy.
NGC 3718 exhibits a warped, S-shape similar to NGC 6872, and has a prominent dust lane obscuring the central bulge. The innermost disc of gas follows the dust lane has a polar orbit around NGC 3718's center, making it a polar-ring galaxy. NGC 3718 is thought to represent an early stage in the evolution of polar-ring galaxies. The unique morphology may be a result of gravitational interaction with NGC 3729, another spiral galaxy located 150,000 light-years away.
