Gravity Physics
True-scale gravity sim
Free · Designed for iPad. Not verified for macOS.
Explore the solar system in true-scale N-body physics. Pilot your ship, fly to distant moons, and watch orbits unfold in real time.
Gravity is a real-time N-body physics simulation of our solar system — fly a spacecraft through accurately modeled orbits, gravity wells, and atmospheres, all rendered in a clean top-down view of the ecliptic plane.
Every body uses real physical data: mass, radius, orbital elements, and atmospheric density where applicable. Gravity between all 26 bodies — Sun, planets, major moons, and dwarf planets — is computed live using velocity Verlet integration, so orbits, perturbations, and gravity assists emerge naturally from physics, not scripted paths.
FEATURES
• Pilot your own spacecraft — configure engine count, thrust, and mass, then launch from Earth
• True N-body gravity — every body pulls on every other body and on your ship, in real time
• Realistic atmospheric drag and heating — feel the difference between skimming Earth's atmosphere and diving into Venus or Saturn
• Time controls — speed up months of orbital motion or slow down to precision-dock in real time
• Trajectory prediction — see where your current heading will take you before you commit
• Flight trail — trace your path across millions of kilometers
• Extended telemetry — track speed, altitude, gravity, thrust-to-weight ratio, dynamic pressure, hull temperature, time dilation, and more
Whether you want to attempt a Hohmann transfer to Mars, slingshot past Jupiter, or just watch the Moon orbit Earth in fast-forward, Gravity gives you a physically accurate sandbox to explore the mechanics of our solar system.
