Thinking in Orders of Magnitude

I am obsessed with creating a game inspired by the likes of Elite, Space Trader, and No Man’s Sky – all about exploration, trading, mining, combat, etc, and in space. I have given up on trying to be very realistic in terms of celestial masses, sizes, and distances – it’s too much for me to handle on my own – but I still want an approximation of this.

One of the problems with this is simply trying to keep track of huge numbers in mind. (Was my “average” planet 107kg or 108kg?) In an attempt to classify and simplify, I ended up creating a chart that sorts objects into 5 broad classes with 5 size-based subclasses within each.

It also conveniently solves a problem I had with trying to keep track of the relative sizes of small planets and large moons, and tiny moons compared to generation ships. There’s a lot of potential overlap between these classes of objects, which is clearly demonstrated. It’s also very nice for setting up orders of magnitude to generate mass or radius values within.

There is a lot of simplification in what I’ve done already, but there is more to be done before I even have a prototype to play with. Perhaps I’ll make a seed-based toy for generating and exploring systems from an overview as the next step.
