51 Peg - System
51 Pegasi b, the first planet found around a Sun-like star. This 1995 hot Jupiter won Michel Mayor and Didier Queloz the 2019 Nobel Prize in Physics.
Halley's Comet
Follow Halley's Comet (1P/Halley) on its 76-year retrograde journey across the Solar System. Trace its dramatic path from beyond Neptune's orbit back toward perihelion in 3D.
The Figure Eight N-body Choreography
Witness the famous Chenciner–Montgomery figure-eight solution: three equal masses endlessly chasing one another along a three-lobed path in periodic gravitational equilibrium.
Red Dwarf Flyby of the Solar System
What if a red dwarf star passed 40 AU from the Sun? Simulate a stellar close encounter and watch how a passing star perturbs planetary orbits and scrambles the Kuiper Belt in 3D.
The Kuiper Belt and Scattered Disc
Journey into the outer Solar System beyond Neptune. Explore dwarf planets Pluto, Eris, Haumea, Makemake, and Sedna on their eccentric, highly inclined trans-Neptunian orbits.
Eris and Dysnomia
Journey 68 AU from the Sun to explore dwarf planet Eris and its moon Dysnomia. Trace the 37,000 km orbit that revealed Eris's immense mass in the distant scattered disc.
