NGC 4463 is an open cluster in the constellation Musca. The young planetary nebula He 2-86 is believed to be a member of the cluster.
-of-sight coincidences. A subsample of "tentative" cases that may potentially be cluster/PN pairs includes Abell 8 and Bica 6, and He 2-86 and NGC 4463.
Theoretical models predict that planetary nebulae can form from main-sequence stars of between one and eight solar masses, which puts the progenitor star's age at greater than 40 million years. Although there are a few hundred known open clusters within that age range, a variety of reasons limit the chances of finding a planetary nebula within
