UGC 12158 or PGC 69533 is an Sb-type barred spiral galaxy located approximately 386,000,000 ly (118 Mpc) away from Earth in the constellation of Pegasus. Its tight spiral disk spans approximately 216,000 ly (66 kpc), whose scale at heliocentric distance is about 36.9 kiloparsecs per arcminute. It is also often stated to resemble the Milky Way in appearance, with a similar central bar and spiral arm structure. The earliest known reference to this galaxy comes from part 2 of the Morphological Catalogue of Galaxies, published in 1964, where it is listed as MCG +03-57-032.
