How to explore Gravitational Slingshot 3D Explorer
Open the Gravitational Slingshot 3D Explorer, read the ~+10 km/s Voyager figure, and scrub periapsis while the craft flies the hyperbola.
- Open https://freetoolonline.com/space-3d/gravitational-slingshot.html and wait for the planet, green velocity arrow, and blue path.
- Read the facts panel: ~+10 km/s teaching delta-v and periapsis in R.
- Scrub Periapsis (R) to bend the flyby more or less.
- Scrub Flyby phase, or press Pause/Play flyby.
- Compare with Hohmann Transfer 3D when you need two burns instead of an assist.
Gravity assist key figures
| Quantity | Value |
|---|---|
| Voyager-Jupiter gravity assist | ~+10 km/s heliocentric gain |
| Flyby path | hyperbolic (single pass, no burn) |
Next: the when guide or vs alternatives. Open the Gravitational Slingshot 3D Explorer.
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
