Overview

ℹ️

SAI 51 is a poorly populated, dense object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as an old cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 16 years.

(*): The parallax distance estimate (~2.24 kpc) differs significantly from the median photometric distance (~0.81 kpc).

Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.
