UGC 12158 or PGC 69533 is an Sb-type barred spiral galaxy located approximately 384,000,000 ly (118 Mpc) away from Earth in the constellation of Pegasus. Its tight spiral disk spans approximately 140,000 ly (40 kpc), whose scale at heliocentric distance is about 36.9 kiloparsecs per arcminute.[2] It is also often stated to resemble the Milky Way in appearance, with a similar central bar and spiral arm structure.[3]
