Overview

ℹ️

SGR 1806-20 is a moderately populated, dense object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 13 years.

(*): The parallax distance estimate (~2.66 kpc) differs significantly from the median photometric distance (~8.86 kpc).

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

Very distant Very young

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, without submm emission.
