- CC3 0.75 High quality
- Clit 0.44 Poorly studied
- Cdup 1.0 Unique
Overview
NGC 6858 is a moderately populated, very loose object of high C3 quality. Its parallax locates it at a very close* distance, below the mid-plane. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature. (*): The parallax distance estimate (~0.46 kpc) differs significantly from the median photometric distance (~2.11 kpc).
Note: This object shares a significant percentage of members with 2 later reported entries. See table with shared members information.
