Overview
ℹī¸
FSR 0238 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is well-studied in the literature.

Note: This object shares a moderate percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
