Welcome to the Apoapsis wiki!

Apoapsis is an interactive web-based star and planetary system generator inspired by Periapsis.

It generates astrophysics-based, seeded procedural systems of main-sequence stars and planets (from tiny moons to brown dwarfs), with configurable parameters, planetary migration simulation, interactive 2D visualization, detailed body inspection, scriptable generation filters, save/load system, and HTML system reports.
