Summary

Theia 817 is a poorly populated, loose object of low C3 quality. It is located at a very close distance from the Sun, above the mid-plane. It was recently reported in the literature.

Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
