Overview

ℹ️

Antalova 1 is a sparse, loose object of intermediate C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a metal-poor, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~1.55 kpc) differs significantly from the median photometric distance (~0.98 kpc).
