Orbit-Simulator

Simulate bodies orbiting a fixed central mass M at the origin. Each orbiter is defined by its start position, velocity and mass. Only F = GMm/r\u00b2 from the center acts on orbiters (no mutual gravity).

• Central body: mass only (presets or custom kg). It does not move.
• Orbiters: editable list — position, velocity, mass per body.
• Integration: velocity Verlet with your time step \u0394t.
• Kepler wedges: equal-time area sweeps; the live wedge follows the body.
