Avedisova suggests that Sh 2-182 is ionised by the B3 Ia supergiant HD 4694
More recent studies, however, conclude that Sh 2-182 appears to be a reflection nebula (not an HII region) and may be associated with the infrared source and protoplanetary nebula IRAS 00470+6429
Sh 2-182 appears to be associated with the infrared source IRAS 00470+6429 which is a protoplanetary nebula.[1
This appears to be a reflection nebula of unknown distance. The CO detected by Blitz et.al. 1982 may not be associated with this object. [2
