When to Use the Proxima Centauri System 3D Explorer - Best Sessions and Limits

Last reviewed: 2026-07-24

Open Proxima Centauri System 3D Explorer when you want to see exactly how close Proxima b, d, and c orbit the Sun's nearest star and why a flare-prone red dwarf complicates the "closest star has a habitable planet" headline - not to model atmosphere retention or a flare's actual radiation dose.

A closest-star session

A session starts by watching the two close-in planets, b and d, and toggling the habitable-zone band to see that b falls inside it while d, orbiting even closer, does not - then triggers a flare to see the radiation-complication story reach every planet at once, and reads the facts panel for the exact distances, periods, and masses.

Sessions this explorer does not fit

Sessions this page does not fit are studying a distant 7-planet resonant-chain system - use the TRAPPIST-1 3D Explorer for that - or modeling actual atmosphere-retention odds under stellar radiation, which no visualization on this site attempts. Walk the controls in the step-by-step guide.

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.
