Overview

ℹ️

Chupina 1 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.

⚠️ 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.

(*): The parallax distance estimate (~0.86 kpc) differs significantly from the median photometric distance (~1.79 kpc).

Relatively close Moderate extinction Near-solar metallicity Very young
