Overview

ℹ️

NGC 6573 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by very high extinction. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 7 years.

(*): The parallax distance estimate (~3.28 kpc) differs significantly from the median photometric distance (~0.46 kpc).

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

Very close Very high extinction Very young

Cantat-Gaudin et al. (2020)
Classified as non-existent in early catalogues. Large discrepancies in distance and age estimates; likely not physical. More details in Appendix A of the article.
