B Hydri was a star among the star systems visible from Earth in the constellation of Hydrus. B Hydri was located in the Great Rift region, and had a planet charted in its orbit that was actually an appearance of the intellivore. A Federation colonization mission dispatched to the planet disappeared, presumably devoured by the intellivore.
- The star's name has the notation of a Flamsteed designated star, with a letter and the constellation's genitive name. However, no stars with letters have been so named in Hydrus in "real life".
