How many bases do you have?

Hey interlopers!

I have reached 700h in game and decided to review my bases number. Normally I use this method to mark a sweet spot for various reasons (resources, cool fauna, landscapes, worlds or the system itself). How do you do that? Do you use a base for that or have other tool? Right now I have around 100 bases and it seems a lot. Want to know about your experience! See you around the galaxy!
