Overview
Theia 1424 is a poorly populated, very 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 is rarely studied in the literature.
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
