☄️ Interstellar Visitor Lab: Hyperbolic Orbits, Excess Speed and Comet Activity

Fly an interstellar visitor through the Sun's gravity well: set excess speed, perihelion, inclination and outgassing, and see why energy ε>0 means a hyperbola (e>1). Presets for ʻOumuamua, 2I/Borisov and 3I/ATLAS (approximate), live orbit plane, coma and curved dust/straight ion tails, brightness and speed graphs, an orbit-fit experiment and a 1e-9 energy check; unlike the generic interstellar-travel pages it models the hyperbolic flyby itself.
