Overview
ℹī¸
FSR 0336 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the distance, age, metallicity, and mass parameters (see Parameters). It is moderately studied in the literature.

Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.
