Space Simulator in 3D: Orbits, Galaxies & Spaceflight
Space is where physics gets grand. These simulations use Newton’s law of gravity, the same maths that steers real spacecraft, so orbits, resonances and collisions behave the way astronomers observe them. Change masses and speeds, or take the controls of a lander, a rover or a rocket, and see the cosmos respond.
-
Solar System in MotionDrag planets onto new orbits and fling new worlds on real gravity. -
Galaxy CollisionAim two spiral galaxies at each other and pull out tidal tails. -
The Three-Body ProblemNudge three stars on one gravity: from a figure-eight to pure chaos. -
Gravity SlingshotLaunch a probe past a giant planet and steal a little of its speed. -
Black Hole Accretion DiskFeed a black hole and watch its glowing disc swirl into the dark. -
Perseid Meteor ShowerCatch Perseid meteors as they streak and trace them back to Perseus. -
Binary Star DanceDrag two stars into new orbits and fling in a planet with two suns. -
Kepler’s Laws: A Comet’s OrbitDrag a comet onto new orbits and see Kepler’s three laws at work. -
Saturn’s Rings and Shepherd MoonsMove Saturn’s moons and throw moonlets through its icy rings. -
Jupiter’s Moons in ResonanceDrag Jupiter’s moons and hear their 1:2:4 beat hold or break. -
Lagrange PointsPlace asteroids at the five spots where they ride along with a planet. -
TRAPPIST-1: Seven Worlds in RhythmDrag seven Earth-sized planets round a red dwarf and hear their tune. -
Earth, Moon and TidesDrag the Moon and watch it raise two ocean bulges on a spinning Earth. -
The Roche LimitCarry a rubble-pile moon too close and watch tides tear it into a ring. -
Lunar LanderFly a lander down to a pad on the Moon and touch down gently. -
Moon Crater MakerThrow asteroids at the Moon and see what size of crater each one digs. -
Rocket to OrbitFly a two-stage rocket from the pad into a circular orbit. -
Space Station DockingSteer a capsule to a space station’s port and dock gently. -
Eclipse MakerSteer the Moon to make its phases, a solar eclipse and a blood Moon. -
Mars Rover DriveDrive a six-wheeled rover over Martian dunes and rocks to its targets.
