Major Features

  • Full Featured Interactive n-body Gravity Simulator.

    • Simulate a moon orbiting a planet, four galaxies colliding together, or an unlimited number of scenarios.
    • It's all to scale and uses real units for measurement: kilograms, meters, seconds.
  • Includes 50+ systems, both real and fictional.
    • Includes the 8 planets, 3 minor planets, 160+ moons, and hundreds of asteroids.
    • Andromeda & Milky Way galaxy collision
    • Easy to edit system files let you create an unlimited number of scenario
  • 3D Mode for red & cyan glasses (anaglyph stereoscopic)
Neptune ripping apart Saturn's Rings
Put on some 3D glasses to see Saturn's rings ripped away by a passing planet.
  • Complete Introduction and included tutorial.
    • Includes 10 activities that explain the various controls.
  • Easy to edit system files let you create an unlimited number of scenarios.
  • Full control of time.
    • Speed it up, slow it down, stop it, start it.
  • Full control of gravity.
    • Increase it, turn it off, triple it, make it negative.
  • Multiple Color Modes
    • Realistic or Bright Color modes
    • View color by velocity or acceleration to help visualize the relative motions of moons and planets.
  • Two collision modes
    • Bounce: A fun, fictional mode where bodies bounce off of each other like big rubber balls.
    • Combine: A more realistic mode where bodies combine into a single body when they collide.
  • Rings systems
    • Rings are simulated as hundreds of particles and are effected by gravity.
    • Includes scale ring systems of Saturn, Jupiter, Uranus, and Neptune.
    • Generate rings around bodies with a single click.
  • Grids
    • Easily create 2D or 3D particle grids and then warp them with Jupiter sized planets.
  • Galaxy Collisions
    • Watch galaxies rip each other apart.
  • Full sky panoramic view of the Milky Way
  • Easy to use interface that's fully controllable with the mouse.
    • Lots of additional keyboard shortcuts.
    • Working Wiimote support
      (Wiimote head tracking support coming soon)
    • Laptop friendly controls
  • Capture high resolution screenshots
    • Combines multiple screen captures into a super high resolution image; 50+ megapixel shots are possible.
    • Tools to capture images sequences
  • Easy Updates
