If you live in Los Angeles (around 33°52’N, roughly the latitude of Hermosa Beach) the black hole in V404 Cygni passes over you each day. On Christmas Day it will be directly overhead around 2pm.

Imagine growing up on a tidally locked world, living in the day, until you wander off for long enough to discover the night.
Hitchhikers guide to the galaxy has an alien species that evolved on a planet (Krikkit)with constant thick dust clouds.
Isaac Asimov also mused about ribbon worlds. ie tidally locked planets with a habitable zone in the twilight regions.
I seem to recall also reading a story about a species on a ribbon world but because of precession had a 10,000 year (or so) day. They had a constant slow migration and eventually started finding the ancient forgotten ruins of their own society.
Also nightfall by Asimov.
Can you remember the name of that 10000 year book? It’s been ages since I’ve read some hard science of the type
I’m sure I read it online it might have just been a scifi writing prompt from the site that must not be named (reddit).
I’m glad Asimov also thought of The Long Street or Eternal Dusk I wondered how wide the strip of settleable territory might be, say on a earth-sized tide-locked planet.
The moon is tide-locked to the earth, but wobbles back and forth, so a tide locked world might also have a day / season cycle where the fringes get extra hot / cold.
I have read a short story about a world with like 9 suns and 3 moons. It’s day all the time, except once every 2000 years, when there is a total solar eclipse. So every 2000 years society falls into chaos, most of the population kills themselves and only rich people, who can afford enough candles/fire or people who are passed out drunk survive the eclipse. At the time the story takes place one astronomer/scientist notices the pattern in their history and like predicts it or something.
Sadly I do not know the link. If anyone recognizes the story I would love to read it again.
