Black Hole Name Generator

Mostly they have catalog designations based on the constellation or survey they were found in, such as Cygnus X-1, V404 Cygni, GRS 1915+105 and TON 618. A few have proper names: Sagittarius A* at the center of the Milky Way, M87* in the Virgo cluster, and Powehi, the Hawaiian name given to M87* after the 2019 Event Horizon Telescope image.

It depends on who in your story named it. Scientists would use a designation like XBH-7 or Carina Maw; crews and colonists would use a blunt nickname like The Drain, The Widow's Eye or Gravewell; an older culture might use a devourer from myth such as Charybdis, Rahu or Fenrir. Interstellar used Gargantua, a giant from Rabelais, which is a good model for a single memorable name.

Yes. The mythological and invented names work for any space-faring RPG, Starfinder or Traveller system, or a fantasy cosmology with a devouring void. The designation-style names are especially useful for star maps where you need dozens of labels that look like they came from the same survey.

Because that is how they behave: matter spirals into an accretion disk and crosses the event horizon without coming back, so words like maw, gullet, throat, sink and drain are natural metaphors, and so are mythic swallowers like Charybdis, Ammit and Jormungand. Most of the English names in this list use one of those images.
