(it’s not a solar system because Sol is our star, specifically; we’re the only Solar system)
TRAPPIST-1 is a cool red dwarf star[c] with seven known exoplanets.
Up to four of the planets – designated d, e, f and g – orbit at distances where temperatures are suitable for the existence of liquid water, and are thus potentially hospitable to life.
The red dwarf star TRAPPIST-1 has an estimated lifespan of pretty much the entire lifespan of the universe. If any of those planets are habitable, and humanity goes there, we could live there until the end of the whole universe, no worrying about our sun going out in about 5 billion years. It could be our forever home.
The planets in the TRAPPIST system are extremely close to each other, so the night sky on any of them would be awe-inspiring, with multiple bodies bigger than our moon rising and setting every night.
In this hypothetical future we’ve learned how to live with an equilibrium. Also we’ve fired all the terminally pessimistic doomers into the Sun. Not for any scientific reason, just because it was the right thing to do.
“If someone disturbs my Sci-fi daydreaming, they are ‘terminally pessimistic’ and it is justified to institutionally murder them” I doubt your values would align with the society you dream of.
