Overview

ℹ️

Basel 5 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.54 kpc) differs significantly from the median photometric distance (~0.85 kpc).

Close Moderate extinction Intermediate age

Cantat-Gaudin & Anders (2020)
Likely an asterism caused by patchy extinction in a dense field; Gaia DR2 astrometry is too dispersed for a real cluster. More details in Appendix A of the article.
