A comet rides an eccentric orbit around the Sun and streams its two signature tails: a straight blue ion tail blown dead anti-sunward by the solar wind, and a curved gold dust tail whose heavier grains inherit the orbital motion and lag along the path. The green coma marks the nucleus; it auto-orbits so the tails swing through perihelion. Steer the push with the pointer; press to shatter the nucleus into an expanding puff.
