How to Use the Voyager Interstellar Position 3D Explorer
Open the Voyager Interstellar Position 3D Explorer, scrub the mission year from 1977 to 2026, and pick either probe - or the heliopause, the Kuiper Belt, Earth's orbit, or the Sun - to read its real NASA JPL distance and dates.
- Open https://freetoolonline.com/space-3d/voyager-interstellar-position.html and wait for the Sun, Earth's orbit ring, the Kuiper Belt, the heliopause, and both probe markers to render.
- Use the Object selector to pick Voyager 1, Voyager 2, the heliopause, the Kuiper Belt, Earth's orbit, or the Sun.
- Drag the Mission year slider (1977-2026) or click "Play Mission Timeline" to watch both probes travel outward.
- Watch each probe marker move along its dashed ray as the distance grows with the mission year.
- Look at the facts panel for the selected object's real distance-as-of date and, for Voyager 1, its one-way radio signal delay.
- Switch objects and compare how far each probe has actually travelled since 1977.

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.
