Overview

ℹ️

OCSN 66 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a very close^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~0.40 kpc) differs significantly from the median photometric distance (~0.64 kpc).

Note: This object shares a very small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
