Overview

ℹ️

LKHalpha 101 is a rich, very dense object of high C3 quality. Its parallax locates it at a close^* distance, below 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 23 years.

(*): The parallax distance estimate (~0.53 kpc) differs significantly from the median photometric distance (~0.80 kpc).

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