About this tool
Binary Star System is a free online visual effect. 3D binary star simulation with barycenter orbit, accretion stream and 3 star type presets. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
Opening the page will show a scene of two stars rotating around a common center of mass. The two stars can be different in size and brightness. Orbital parameters, stellar properties, etc. can be adjusted.
The whole process is purely front-end animation, drawing binary stars based on Canvas and calculating positions using Kepler's orbital equations.
It is suitable for use as astronomy science, double star theme decoration, or purely appreciating the beauty of motion of the double star system. The implementation principle is an analytical solution to the two-body problem.
The binary star system is a visual effect that simulates two stars orbiting each other. It renders the motion of the binary star in real time based on Canvas.
