Overview

ℹ️

Sct OB3 is a moderately populated, moderately dense object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high 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 8 years.

(*): The parallax distance estimate (~3.24 kpc) differs significantly from the median photometric distance (~1.48 kpc).

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