How to Explore Coronal Mass Ejection 3D Explorer

Reviewed by

Open the Coronal Mass Ejection 3D Explorer, scrub CME speed, then play or drag progress as the cloud expands from the Sun toward Earth and read the travel-time estimate.

  1. Open https://freetoolonline.com/space-3d/coronal-mass-ejection.html and wait for the Sun, Earth, and orange particle cloud to paint.
  2. Drag CME speed toward 2500-3000 km/s and note the travel-time estimate moving into the 15-18 hour fast-arrival ballpark.
  3. Press Play (or Pause) and watch progress climb; or drag Progress from 0% toward Earth.
  4. Reset to restart from the Sun, then try a slower scrub near 250-800 km/s to see multi-day arrivals.
  5. Read the facts panel for <250 to nearly 3000 km/s, 15-18 hours, several days / ~1-3 days, and billions of tons (~1e16 g class).

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.
