Voyager Interstellar Position 3D Explorer vs alternatives
Voyager Interstellar Position 3D Explorer animates 49 years of travel for both probes side by side on one compressed scale so a reader can compare their heliopause-crossing dates at a glance - NASA JPL's own Voyager mission status page wins for today's continuously updating live distance counter; a printed distance table wins as a fixed citable reference with no rendering required.
| Option | Strength | Access | Trade-off |
|---|---|---|---|
| Voyager Interstellar Position 3D Explorer (this page) | Animated side-by-side comparison of both probes' outward travel since 1977 in one 3D scene | Free, in browser | Distance figures are fixed as of a stated date, not a live counter |
| NASA JPL Voyager mission status page | Continuously updating live distance counter for each probe | Free, official source | No 3D teaching visualization of the launch-to-heliopause journey |
| Printed distance table | Fixed, citable reference figures | Reference texts/papers | No animated comparison of how the gap between the two probes grew over time |
Key published figures
| Figure | Value |
|---|---|
| Voyager 1 distance | about 170 AU as of 2026-01-09 |
| Voyager 2 distance | about 142.5 AU as of early 2026 |
| Voyager 1 one-way signal delay | about 23.5 hours |
| Voyager 1 one-light-day milestone | expected around 2026-11-18 (about 173.8 AU) |

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.
