Overview
Theia 5 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a very close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, near-solar metallicity, very young cluster (see Parameters). It was recently reported in the literature.
â ī¸ Warning: This is very likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.
