About this Simulation

This interactive JavaScript model visualises the gravitational interaction between two stars orbiting their common centre of mass. Learners can adjust orbital parameters and observe how gravitational forces govern binary star motion, exploring concepts of orbital period, mass ratios, and dynamic equilibrium in two-body systems.

Learning objectives: Understand how gravitational forces maintain stable orbits in binary star systems | Investigate the relationship between mass, orbital radius, and orbital period | Analyse the motion of stars around their centre of mass
