BDSB 99 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 13 years.
Note: This is very likely a unique object, which shares a very small percentage of members with at least one previously reported entry, and a very small percentage with at least one entry reported in the same catalogue. See table with shared members information.
