About

Project Gaia is an open source tool for the creation of fictional solar systems.
With just a few inputs it creates many of the physical characteristics of stars, planets and moons without you having to spend your time crunching numbers.
Project Gaia also visualizes some of the characterics like the size and color of stars, the composition of planets or their orbits.
The Tool will also give you some feedback about the realism of your system (which you are of course free to ignore and handwave away ;) ).

Project Gaia runs fully online.

How to use the tool

All units are if not noted otherwise relative to our solar system:

• Sun (☉)
• Earth (🜨)
• Moon (☾︎)
• Astronomic Units (AU) = Distance between the earth and the sun.
• Lunar Distances (LD) = Distances between the moon and the earth.

Just enter the data of your world and let the system calculate the rest.
Once you have build your stars and planets you can put them into orbit and then add moons.
Remember to save your progress before closing the page.

Anyway... Happy Worldbuilding!
