Overview

ℹ️

Theia 2727 is a moderately populated, loose object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It was recently reported in the literature.

Note: This object shares a significant percentage of members with a later reported entry. See table with shared members information.
