How to explore Solar Wind Heliosphere 3D Explorer

Open the Solar Wind Heliosphere 3D Explorer, locate the termination shock and heliopause spheres, and scrub the ~400 km/s wind readout.

Open https://freetoolonline.com/space-3d/solar-wind-heliosphere.html and wait for the Sun plus nested cyan/magenta spheres.
Read the facts panel: termination shock ~94 AU, heliopause ~121 AU (Voyager 1, 2012), wind ~400 km/s.
Click the cyan shock sphere, magenta heliopause, or Voyager marker for boundary details.
Scrub Wind between 200 and 800 km/s and watch the outward particle stream rate change.
Press Pause wind to freeze particles, Hide labels to clear AU callouts, then AU table for the summary.

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.
