Overview
Theia 3118 is a moderately populated, loose object of very high C3 quality. Its parallax locates it at a moderate* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
â ī¸ Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.
(*): The parallax distance estimate (~3.06 kpc) differs significantly from the median photometric distance (~2.35 kpc).
