☄️ Near-Earth Asteroid Orbit Lab: MOID, Close Approach, Gravitational Focusing and Yarkovsky Drift

Shape a heliocentric Kepler orbit in 3D, compute its MOID with Earth, follow the close approach and the RK4 flyby bent by Earth's gravity, let the Yarkovsky transverse force shift the timing over decades, and read a b-plane uncertainty cloud with a Torino-style intuition meter. Experiments compare simulated Yarkovsky drift with the Gauss-equation formula.
