KjPN8 (PNG112.5-00.1) is a rare, unusual and extremely weak bipolar planetary nebula in the constellation Cassiopea. KjPn 8 represents the first case where two distinct and consecutive planetary nebulae-like events have been detected simultaneously, probably originating from a binary core evolution with components of very similar mass and thus evolving nearly in parallel. These characteristics indicate that KjPn 8 may be a rare object in our galaxy and the first ever detected of this class.
