Reference / orbital field guide
Find your way around the solar system.
Start with your first orbit, find a control, or follow a question into the physics. Source and build references are here when you need them.
ORBIT MANUAL / FIELD NOTES
New here? Watch your first orbit.
Choose Earth and the Moon, pause the scene, and discover how motion changes your view. You do not need to know the equations or write any code to begin.

MANUAL_01
Start here
Watch your first orbit, choose a question, and get help with the controls.
MANUAL_02
Physics & view
Trace SI-unit state through integration, rendering scale, vectors, and trails.
MANUAL_03
