Proxima Centauri System 3D Explorer vs alternatives
Proxima Centauri System 3D Explorer animates all 3 known/candidate planets on their real relative orbits with a live habitable-zone band and flare toggle in one 3D scene - a textbook diagram wins as a fixed printed reference, and the TRAPPIST-1 3D Explorer wins when the question is about a different, more distant multi-planet system.
| Option | Strength | Access | Trade-off |
|---|---|---|---|
| Proxima Centauri System 3D Explorer | Real b/d/c orbits, habitable-zone band, flare toggle | Free, in-browser, no account | Enlarged bodies and a compressed, non-linear distance scale |
| Physics/astronomy textbook diagram | Fixed printed reference, full citations | Requires the book | No interactivity, one snapshot only |
| TRAPPIST-1 3D Explorer (this site) | 7-planet resonant chain, a genuinely distant system | Free, in-browser | Different system entirely - about 40 light-years away, not the Sun's nearest star |
Key published figures
| Figure | Value |
|---|---|
| Distance from the Sun | 4.2465 light-years |
| Proxima b | 11.2-day orbit, inside the habitable zone |
| Proxima d | 5.12-day orbit, too close/hot |
| Proxima c | ~5.28-year orbit, unconfirmed, too cold |

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.
