About this tool
Three-Body Problem is a free online visual effect. N-body gravitational chaos simulation with figure-8, Lagrange, chaotic and hierarchical presets. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
After opening the page, it will show that three celestial bodies are moving under the influence of mutual gravity. The motion trajectory shows chaotic characteristics and its long-term behavior is unpredictable. Parameters such as initial conditions and gravitational constants can be adjusted.
The whole process is purely front-end animation, based on Canvas 'N-body simulation, using numerical integration to calculate the motion trajectory of each celestial body.
It is suitable for use as astronomy science, chaos theory display, or purely appreciating the chaos beauty of the three-body problem. The realization principle is the numerical integration of Newton's gravitational equation.
The three-body problem is a visual effect that simulates the motion of three celestial bodies under the action of gravity, demonstrating the unpredictability of chaotic motion.
