How this entity was disambiguated

This entity first appeared as the object of triple T19260608 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A. Orcus–Vanth system
The Orcus–Vanth system is a binary Kuiper Belt object consisting of the dwarf-planet candidate Orcus and its large moon Vanth, notable for their relatively similar sizes and tight mutual orbit.
B. Kuiper Belt object Arrokoth
Kuiper Belt object Arrokoth is a distant, bilobed trans-Neptunian world famously visited and imaged in detail by NASA’s New Horizons spacecraft after its Pluto flyby.
C. dwarf planet Orcus
Dwarf planet Orcus is a large Kuiper Belt object beyond Neptune, often compared to Pluto for its similar orbit and characteristics, and is accompanied by its moon Vanth.
D. Plaskett’s Star
Plaskett’s Star is a massive, highly luminous spectroscopic binary system composed of two very hot O-type stars, notable as one of the most massive known binary star systems in the Milky Way.
E. pula–thebe system
The pula–thebe system is the decimal currency structure of Botswana, in which the pula is the primary unit and the thebe is its subdivision.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
