How it works
A stylized top-down view of the Sun and the eight major planets. Each body moves on a circular orbit with period equal to its real sidereal period (Kepler’s third law in years). Distances use a logarithmic mapping in astronomical units (AU) so both Mercury and Neptune stay on screen. This is a teaching model — not a scale-accurate N-body integrator.
Key equations
θ = (2π / T) · t + φ
r_orbit ∝ log(a) display mapping (AU)
