Overview
Theia 2133 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a moderate distance, above 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 is very likely a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.
