A quick question for #worldbuilding, but does anyone know of a good, โ€˜easyโ€™ #starsystem / #solarsystem generator?

By good, I mean one that can and will create a star system with possibly unlivable planets (I don't care if its vivable or not)) depending on the size of the star (very important)?

If it doesn't exist, I'll go back to my dice and chance, but it's worth a try ?

Thank you very much ! :D

I'm a writer, and one of the things I use social media for is to promote my own work.

I also know how annoying it is when authors never post anything *else*. So I limit myself to one post a week. That's today.

Here's my most recent book, published by Ad Astra Games. This is my current last word on designing scientifically plausible exoplanetary systems for fiction, at least until I produce a second edition.

Recent discussions about hypothetical D&D economies led me to look into Roman currency. Here is a great wikipedia image of the common currency in the 27 BC - 100 AD Roman era.

So instead of copper, silver, electrum gold (the D&D standard), the early Roman Empire used various iterations of Bronze, Orichalcum, Silver, Billon, and Gold.

And today I learned Billon is the name for an alloy of silver and gold, or silver and copper, or silver and gold and copper, or basically any alloy of silver and some base metal.

Painting worlds in that unfortunately named free image editing software, you know the one.
Anyway, Astrosynthesis slaps an image around a sphere and a world is born, see it spin prettily in Space....

The habitable moon called 'Auburn Falls' rotates slowly in it's orbit, the red light of it's primary tinging the Earth-like world slightly purple in the seas. Note also the orbital infrastructure, although Astrosynthesis doesn't allow such things to be accurate represented, at least they're there. Auburn Falls has a Loftstrom Loop (conventional space elevators are difficult for moons) and an cluster of space habitats, left over from when the moon was being transformed by the famed terraformers of Welcome Systems.
I love it when fiction authors include:
* maps
* organizational charts
* profiles of characters with little images
* family trees
* timelines
* diagrams of weapons and ships with all the features labeled

I sometimes think there is some notion that such things arenโ€™t โ€œreal writingโ€ or even that they are โ€œcrutchesโ€

But really itโ€™s just enjoyable and makes the world seem more real.

@futurebird I just enjoy Worldbuilding for the hell of it, barely has any story come of my Universe but it is a vast and documented place. I know there are others like me.

There is a subgenre of academic papers that could have originally started as someoneโ€™s homework for a #SciFi story or #worldbuilding exercise. This exploration of constraints on #life beyond Earth definitely fits that category.
Also, seriously, #writers , so many excellent resources now to explore and understand how life outside Earth could evolve and functionโ€ฆ if you want to go for hard SciFi (or just get some out-of-the-box ideas), just reach out and grab them.

The planet 'Brick Garden', so called for the continent sized fungal ecosystem that turns part of the world purple, one of the more ubiquitous species looks like a brick garden of fungal creations.

The planet Brick Garden slowly spins in space, a mostly earth like world of clouds and inland seas. A purple strip stretches from north to south and rotates into view.

Messed around with making a zodiac constellation chart for my homebrew campaign. It probably will not come up in play but I sometimes think just making things lends a certain versimilitude to the game. Plus, it might lead to other ideas.

I based the zodiac after the real zodiac but sometimes changed the names, sometimes changed the constellation to be one very near, or sometimes made it up.

Now that I am done, I can not rule out that maybe The Elder Scrolls influenced my choices in some subconscious sort of way.

#WritersCoffeeClub 26: Do real-life events inspire your writing? Share an example.

As Ken Macleod remarked, "history is the secret weapon of the science fiction writer".

Not every time, not for every story element, but it's an *amazing* toy box that you can borrow from whenever you're stuck for an idea! Because fiction illustrates the human condition and humans get up to some really weird shit, for values of "you can't make that up" weird.

@cstross
These #history deep-dives by #IsaacAsimov are great reads and illustrate your point about using our actual world for #worldbuilding in #SciFi.

As a reminder, when doing #ttrpg #worldbuilding , it's usually unnecessary to have human(oid) history go back "tens of thousands of years". If you need some justifications for old ruins and whatnot, it's easy to cram them into the last thousand years or less. Real world history is _full_ of interesting stuff happening in fairly short time periods, so it's not difficult to arrange the same for fictional worlds.

Besides, humans constantly come up with new ideas and new technology. If you _want_ human society in your fantasy world to have a typical late medieval/Renaissance-era tech level, then you will need to come up with some good reasons why they haven't developed further - and that gets trickier the longer the history of human civilization in your world is.

Been manually entering the moons of Saturn into an Astrosynthesis map, the Application allows one to build a 'system orbit map' and you see here how the Saturnian system works, how little moons shepherd some of the rings.
The map reminds me of playing Frontier: Elite II back in the 90s, travelling the stars. Now I have the ability to make my own maps, a dream I had back as a youth. 90s me would love this shit
