When to Use the 2I/Borisov Interstellar Comet 3D Explorer - Best Sessions and Limits

Last reviewed: 2026-07-25

Open the 2I/Borisov Interstellar Comet 3D Explorer when you want to compare a confirmed interstellar visitor's unbound orbit and unusual coma chemistry against a typical bound solar-system comet - not to track 2I/Borisov's current position (it left the solar system years ago).

A composition-and-orbit contrast, not a live tracker

A session starts by toggling to 2I/Borisov to see its hyperbolic eccentricity of about 3.36 and its CO-rich coma (about 35-155% CO/H2O), then toggling to Halley's Comet to see a bound eccentricity of about 0.967 and a typical 4% CO/H2O ratio - while the comparison table stays fixed, ranking both objects side by side.

Sessions this explorer does not fit

Sessions this page does not fit are tracking 2I/Borisov's current position (it passed perihelion in December 2019 and is now leaving the solar system forever) or 1I/'Oumuamua's own shape and tumbling story, which is on the 'Oumuamua 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.
