How to Explore the 2I/Borisov Interstellar Comet 3D Explorer
Open the 2I/Borisov Interstellar Comet 3D Explorer and toggle between 2I/Borisov and Halley's Comet to compare each object's real orbital eccentricity and coma composition side by side.
- Open https://freetoolonline.com/space-3d/borisov-interstellar-comet.html and wait for both comet models and the Sun to render.
- Drag the toggle switch (0-1) to swap the highlighted comet between 2I/Borisov (blue-tinted coma, open path) and Halley's Comet (orange-tinted coma, closed loop).
- Read the facts panel for the active comet's real orbital eccentricity, perihelion distance, speed, and CO/H2O ratio.
- Check the comparison table below the facts panel - the highlighted row is the active comet.
- Notice the two path curves: Borisov's open hyperbola never closes, while Halley's ellipse loops back around the Sun.
- Drag to orbit and scroll or pinch to zoom to see each comet's coma density up close.
Key published figures
| Figure | Value |
|---|---|
| Orbital eccentricity (2I/Borisov) | about 3.36 (hyperbolic) |
| Orbital eccentricity (Halley's Comet) | about 0.967 (bound) |
| CO/H2O ratio (2I/Borisov) | about 35-155% |
| CO/H2O ratio (typical comet) | about 4% |

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.
