REBOUND optimizes computation. Orbital Symphony optimizes comprehension.
Orbital Symphony is an interactive scientific instrument for exploring orbital dynamics, chaos, and multi-body gravitational systems through visualization, experimentation, and sonification.
It is built for people who want to understand why systems become unstable, diverge, resonate, or collapse — not just compute trajectories.
Early development — MVP in progress.
First public prototype is currently being built.
Current focus:
- 2-body simulation engine
- 3-body simulation engine
- RK4 numerical integration
- Perturbation compare mode
- Sonification Engine v1
Many existing orbital mechanics tools are excellent at numerical simulation.
But there is still a gap:
- Why does a tiny perturbation create a radically different future?
- When does stability become chaos?
- Why does prediction fail?
- How can humans see and hear complex dynamics?
Orbital Symphony focuses on these questions.
Orbital Symphony is not trying to replace professional astrophysics software.
It is designed as a:
Scientific instrument for intuition, exploration, education, and chaos perception.
Run two nearly identical systems side-by-side.
Change one tiny initial condition and watch their futures diverge over time.
Perfect for understanding:
- sensitivity to initial conditions
- chaotic growth
- prediction limits
Quantify separation over time:
- trajectory distance
- divergence curves
- instability indicators
- escape thresholds
Interactive views for:
- 2D orbit maps
- 3D scenes
- orbit trails
- barycenter motion
- rotating reference frames
Sound is a first-class analytical layer — not decoration.
Orbital Symphony converts system dynamics into sound so users can hear transitions, instability, resonance, and chaos.
| Physical Property | Sound Mapping |
|---|---|
| Velocity | Pitch |
| Total Energy | Volume |
| Chaos Intensity | Distortion / Noise |
| Resonance Lock | Harmony |
| Near Collision | Tension rise |
| Escape Event | Sharp break / burst |
- Detect transitions faster
- Build intuition through hearing
- Accessibility support
- Memorable learning experience
- New perception channel for nonlinear systems
Observe:
- resonance emergence
- near-collision instability
- escaping bodies
- periodic vs quasi-periodic motion
- transition to chaos
Get “aha moments” beyond equations.
Use alternative perception tools + exportable experiments.
Live demos of chaos and orbital mechanics.
Explore gravity creatively.
Orbital Symphony does not claim to be:
- mission-grade astrodynamics software
- a replacement for professional research solvers
- a long-horizon predictor of chaotic systems
- a flight-critical decision system
It is a tool for understanding, not false certainty.

Orbital Symphony does not promise to tame chaos.
It lets humans see it, hear it, and understand it.
