Drag the bodies and their velocity arrows to fill the band.
First Lightfill ≥ 62% to win
One heavy sun, one probe. The sun is fixed — just aim the probe's velocity so it settles into the orbit that fills the band.
Grab a glowing body to move it, or drag the tip of its arrow to aim its launch velocity. The cyan corridor is your target — get the white-ringed probe's trail to fill it, then Launch.
How it works
Each body pulls every other by Newtonian gravity (softened so close passes don't blow up), integrated with velocity-Verlet. Three bodies have no general closed-form solution — tiny changes to the start send the paths wildly apart, which is exactly the chaos you're taming. The band is the path a known-good launch traces, so every level is solvable.
