Overview

ℹ️

Nuclear Star is a moderately populated, moderately dense object of low C3 quality. Its parallax locates it at a moderate^* 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.

(*): The parallax distance estimate (~2.37 kpc) differs significantly from the median photometric distance (~8.23 kpc).

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.

Very distant

Morales et al. (2013)
Classified as morphological type 'EC1' (deeply embedded cluster). Morphological flag: cluster fully embedded.
