DYNAMIC GRAVITYTakes the focused system off its Keplerian rails and integrates real N-body gravity: every mass pulls on every other mass. Orbits go unstable, get captured, get torn apart. Leapfrog integration at 1/24 of the fastest orbit. Pair it with COLLISION PHYSICS.
COLLISION LABImpacts report their energy in tonnes of TNT and their closing speed. Ejecta becomes real bodies on ballistic paths: inside the Roche limit they spread into a ring system, outside it they are captured as moons, and everything that falls back accretes.
HABITABLE ZONEThe green band around every star, from its measured luminosity (Kopparapu limits). The CLIMATE MODEL row recomputes equilibrium temperature from real stellar flux, albedo and greenhouse at every step.
LAGRANGE POINTSL1–L5 for the world you are focused on, with the triangular points at ±60°.
ORBIT PREDICTIONDraws 1.6 orbits of the selected body's future path.
SNAPSHOT / RESTORERecords the whole universe — masses, radii, orbital phase, velocities — and puts it back. Undo a catastrophe.
MINOR BODIESRenders the asteroid and outer icy belts for the system under observation.
SIMULATION LIBRARYTwelve staged experiments: giant impact, comet bombardment, binary stars, the three-body problem, a black hole encounter, colliding galaxies, the Roche limit, the habitable zone, Planet Nine, an impact laboratory, a supernova and a 100-million-year stability run.
SEARCHThe box in the top bar finds any of the 7 254 stars, 2 268 confirmed worlds, 829 galaxies or 24 structures and travels straight to it. Arrows to browse, ENTER to go.
TRANSITS & ECLIPSESWhen a world crosses the disc of its star, or a moon enters a planet's shadow, the event is logged as you observe it.
PHOTO MODE PHides every instrument for a clean capture.
