Overview
ℹī¸
Collinder 107 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is very well-studied in the literature.

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