Overview

ℹ️

NGC 281W is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 23 years.

⚠️ 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 (~2.98 kpc) differs significantly from the median photometric distance (~2.10 kpc).
