Overview
Theia 71 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a very close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.
Note: This object shares a very small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
