How to Explore Impact Crater Formation 3D Explorer

Reviewed by

Open the Impact Crater Formation 3D Explorer, compare Barringer, Chicxulub, and Vredefort at a shared scale, then drag the impactor slider to grow a test crater.

  1. Open https://freetoolonline.com/space-3d/impact-crater-formation.html and wait for the ground plane plus three crater rims to paint.
  2. Click the smallest rim - Barringer Crater, about 1.19 km across and 50,000 years old.
  3. Click the mid-size rim - Chicxulub, about 180 km across and 66 million years old, the end-Cretaceous impact.
  4. Click the largest rim - Vredefort Dome, about 300 km across (original estimate) and 2.02 billion years old.
  5. Drag the impactor-diameter slider from 50 m toward 15 km and watch the red test crater grow using the 20x scaling rule.

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.
