HD 181342 b is an extrasolar planet orbiting the K-type star HD 181342 approximately 394 light years away in the constellation Sagittarius.[1][3]
The planet HD 181342 b is named Dopere. The name was selected in the NameExoWorlds campaign by Senegal, during the 100th anniversary of the IAU. Dopere is an expansive historical area in the north of Senegal where Belel (name of HD 181342) was located.[4][5]
