Overview

ℹ️

Carraro 1 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by low extinction. It is catalogued as a low-mass, old cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~3.12 kpc) differs significantly from the median photometric distance (~1.79 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.

Relatively close Low extinction Low mass Old
