Simulates Ulysses from Earth to Jupiter, then the gravity assist that cranked the spacecraft into a 76° solar polar orbit over the Sun’s poles.
Uranus and Its Moons
Simulates Uranus rolled on its side (98° tilt) with Miranda, Titania, Oberon, and the inner shepherd moons orbiting in that extreme equatorial plane.
Uranus at 2 AU
Simulates Uranus moved to 2 AU between Mars and Jupiter, with the other planets in their real 1 January 2025 positions — an ice giant dominating the middle Solar System.
