Overview

ℹ️

BDSB30 is a rich, very dense object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.

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