The Pilgrim Star is the system where, in the game's very earliest days after release, one player decided to try walking all the way around a planet, using only the stars and a compass as guide. He documented his journey:

It got some news writeups and he streamed the last hour of the journey.
The planet Dudenbeaumodeme has regenerated multiple times since then. But there is still a planet there, and I get to wondering what it's like these days.
The journey to the Pilgrim Star goes quickly, and I soon have an answer as to what the historic planet is like these days: a world of blue grasslands and near constant rain, kinda miserable but pretty in a way. No bases here but a few player messages wondering what's become of the planet, and a few others buried inaccessibly deep beneath the long since regenerated terrain, probably marking some now-vanished base.
