Coronal Mass Ejection 3D Explorer vs alternatives
The Coronal Mass Ejection 3D Explorer shows CME speed and Sun-to-Earth travel time in the browser with NOAA SWPC / NASA GSFC figures - textbooks and SWPC briefings win for operational forecasts; desktop MHD codes win for physics runs.
| Option | Strength | Access | Trade-off |
|---|---|---|---|
| CME 3D (this page) | Speed scrub + progress play + published travel-time table | Free, in browser | Compressed scale; not an MHD forecast |
| NOAA SWPC / NASA briefings | Operational alerts and observed event lists | Free, research-oriented | No interactive teaching cloud |
| Desktop MHD / heliophysics code | Physics-based wind and CME runs | App / install / research cluster | Heavy setup; not a quick explorer |
Key published figures
| Figure | Value |
|---|---|
| CME speed range | <250 to nearly 3000 km/s |
| Fastest Earth-directed arrival | 15-18 hours |
| Slower / typical arrival | several days; common ~1-3 days |
| Mass scale | billions of tons (~1e16 g class) |
Start with the step-by-step guide or when to use. Open the Coronal Mass Ejection 3D Explorer.

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.
