Overview

ℹ️

Platais 2 is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a relatively close^* distance, well below the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~1.91 kpc) differs significantly from the median photometric distance (~0.20 kpc).
