Overview

ℹ️

NGC 281 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by low extinction. 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 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 (~3.03 kpc) differs significantly from the median photometric distance (~1.43 kpc).

Relatively close Low extinction
