☄️ Asteroid Intercept Dynamics: 2D Orbit and Deflection Lab

2D companion of Asteroid Intercept Dynamics: a kinetic impactor changes an asteroid's orbit and the simulator propagates Kepler orbits to find the Earth miss distance, the capture radius with gravitational focusing and the required push versus warning time. Educational planetary-defence physics.
