SH2-209 is a rather remote H II region, located on the arm of the Swan at a distance of about 7800 parsecs (a little less than 25500 light years). It is part of a star formation region located on the periphery of the Milky Way, to which associated with some sources of infrared radiation cataloged by IRAS. Among these, IRAS 04064+5052 stands out, coinciding with a young stellar object identified in 1989 and having the initials CPM 12, which is associated with a maser with H2O emissions; the nebula also hosts the young open cluster [BDS2003] 65, still deeply immersed in the gases
