Orbital Tools – Real-time Keplerian Orbit Simulation for Godot 4

Add two powerful 3D nodes to Godot Engine: OrbitalObject3D and OrbitRender3D, and instantly get realistic orbital mechanics without writing a single line of physics code.>span class="css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3">Sphere of Influence (SOI) switching, exactly like Kerbal Space Program. Everything runs automatically, in real-time, and with minimal setup.Key Features

• Fully automatic patched conics (SOI transitions) – fly from a moon surface to interplanetary space seamlessly
• True Keplerian orbits: elliptical, parabolic, and hyperbolic trajectories
• Realistic orbital parameters (semi-major axis, eccentricity, inclination, LAN, argument of periapsis, true anomaly…)
• Time-warp friendly: orbits remain perfectly accurate even at millions of × speed
• Orbit prediction line with apoapsis/periapsis markers and configurable length
• Multiple celestial hierarchies: stars → planets → moons → satellites → spacecraft
• Easy maneuver node creation (change velocity at any point and instantly see the new orbit)
• Supports any scale (from small satellites to entire star systems)
• 100 % GDScript – lightweight, no C++ modules or external dependencies
• Works out-of-the-box with Godot 4.3+

Perfect for

• Kerbal Space Program-style games
• Space flight simulators
• Educational orbital mechanics visualizations
• Tech demos and prototypes involving satellites, stations, interplanetary transfers, gravity assists, etc.

Just drop the nodes in your scene, set mass and initial position/velocity (or classical orbital elements), and watch physics-perfect orbits appear instantly.Simple, fast, and incredibly powerful. Start building your own solar system today! (Compatible with Godot 4.3 and newer – fully open source – regular updates)
