Overview

ℹ️

LK 10 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-rich, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~1.59 kpc) differs significantly from the median photometric distance (~2.52 kpc).

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