Part of Orion Nebula, situated in the outskirts of the Trapezium Cluster (age 1 Myrs), in the Dark Bay region, at approximately, 4.4 arcminutes (around 0.5 pc, at 390 pc) in projected separation to the north-east of the O6V star 𝜃¹ Ori C and 5.2 arcminutes from the O9.5IV star 𝜃² Ori A. The object is also in closer projected separation to *V2445 Ori (18.8 arcseconds or 7,356 AUs at 390 pc).
270-1954 is likely a highly extincted, low-mass brown dwarf or massive gas giant at the head of a dark trail extending approximately 1700 AUs in length to its north-east and ∼48-72 AUs in width.
