Overview

ℹ️

S 283 is a poorly populated, moderately dense object of high C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 9 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 (~5.21 kpc) differs significantly from the median photometric distance (~3.52 kpc).
