Jupiter and the Galilean Moons
Simulate Jupiter and its four Galilean moons: Io, Europa, Ganymede, and Callisto. Watch the historic 4:2:1 Laplace orbital resonance play out in interactive Newtonian 3D.
Makemake and MK2
Venture into the Kuiper Belt to explore dwarf planet Makemake and its elusive moon MK2. Follow their mutual orbit 45 AU from the Sun in this accurate gravitational simulation.
Mars and Its Moons Phobos and Deimos
Simulate Mars and its doomed moons, Phobos and Deimos. Watch swift Phobos skim just 6,000 km above the Martian surface while outer moon Deimos traces a serene 30-hour orbit.
Neptune and Its Moons
Explore Neptune's moon system, dominated by massive retrograde moon Triton. Discover the captured Kuiper Belt origins of Proteus, Larissa, and highly eccentric Nereid in 3D.
Pluto and Its Moons
Explore Pluto and its five moons: Charon, Styx, Nix, Kerberos, and Hydra. Witness a true binary dwarf planet whose barycenter floats in open space outside Pluto itself.
Saturn and Its Moons
Explore Saturn, its major moons including Titan and Enceladus, and thousands of dynamic ring particles. Watch gravitational shepherd moons carve distinct gaps across the rings.
Shoemaker-Levy 9 Impacts Jupiter
Witness Comet Shoemaker-Levy 9's historic 1994 collision with Jupiter. Track 21 fragmented icy nuclei plunging into the gas giant's atmosphere at 60 km/s in realistic 3D.
The Earth and Moon System
Explore the Earth-Moon system in precise Newtonian 3D. Watch our tidally locked Moon orbit at 384,400 km while solar gravitational perturbations subtly modulate its orbital path.
Uranus and Its Moons
Explore Uranus and its ring-moon system, tilted 98 degrees on its side. Watch Miranda, Ariel, Titania, Oberon, and shepherd moons orbit in the planet's extreme equatorial plane.
