When to Use the Fireball / Atmospheric Entry 3D Explorer

Last reviewed: 2026-08-02

Open the Fireball / Atmospheric Entry 3D Explorer when you want to test a diameter, speed, or angle that is NOT one of the site's fixed historical cases, and see where the model places the ablation onset for that specific combination.

Sessions this explorer fits

Students asking "what if the body were twice as big" or "what if it came in steeper", teachers demonstrating that outcome depends on diameter more than on angle, and curious readers who want to drag the diameter slider up and watch the outcome band flip from harmless to Chelyabinsk-class all get a direct answer from the sliders - no fixed case required.

Sessions this explorer does not fit

Sessions this page does not fit are watching the real 2013 Chelyabinsk event unfold on its own actual timeline, which is on the Chelyabinsk Meteor 3D Explorer, or comparing three specific real historical cases side by side on one shared altitude scale, which is on the Meteor Airburst Size Comparison 3D Explorer. Walk through the controls in the step-by-step guide.

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.
