Overview
Theia 3779 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.
â ī¸ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.
