An unusual planetary. The host star is an “O6.5f” type. Apparently, only about 5 such stars are known – 3 in the Milky Way and 2 in the SMC. It lies about 4,200 ly away. Estimated to be only about 4 million years old it has perhaps another 3 million years left.

With a mass 40 times that of the sun it is a supernova candidate.
