Sci-Fi Generator – Star System and Planet Generator

Publisher: Ennead Games

“Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space…”

Douglas Adams, The Hitchhiker’s Guide to the Galaxy

You are out there, being busy and exploring the big an empty void known as space and you encounter a star. What type of star is it? How many planets, if there are any, are in orbit?

What about the planets themselves?

Disclaimer

Due to how complex the nature of star systems and planets can be in real life, this publication is not claiming in any way to be scientifically 100% accurate…at all. This is a deliberate design choice, to make it easier to use and not bogged down with too much detail.

At the end of the day, this publication is for fun and idea prompting and assistance. If you need 100% accuracy, there are plenty of free books, websites and resources out there worthy of your time and attention.

Also, this PDF is an updated and combined version of parts of the Multi-Verse Kit Part 3 and 4, from Ennead Games. Some parts have been removed, such as the sentient life/cultures chapter and others changed, but the majority of the content has been used. If you have those titles, you have most of this already.
