Overview

ℹ️

SAI 50 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a very old cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 16 years.

(*): The parallax distance estimate (~2.19 kpc) differs significantly from the median photometric distance (~21.90 kpc).

Note: This object shares a moderate percentage of members with a later reported entry. See table with shared members information.
