Overview

ℹ️

Orion Nebula is a moderately populated, very dense object of low C3 quality. Its parallax locates it at a very close distance, below the mid-plane. No fundamental parameter values are available for this object. It is rarely studied in the literature, with no articles listed in the last 23 years.

Note: This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry, and a significant percentage with at least one entry reported in the same catalogue. See table with shared members information.
