3I/ATLAS Interstellar Object 3D Explorer vs Alternatives
The 3I/ATLAS Interstellar Object 3D Explorer ranks all three confirmed interstellar objects' real measured eccentricity, size, and coma activity in one scaled 3D scene - NASA's own 3I/ATLAS Facts and FAQs page wins as the source for official figures; the dedicated 'Oumuamua and Borisov explorers win for either object's own full story, not a three-way comparison.
| Option | Strength | Access | Tradeoff |
|---|---|---|---|
| 3I/ATLAS Interstellar Object 3D Explorer (this page) | Side-by-side comparison of all three known interstellar objects in one scaled 3D scene | Free, in the browser | Summarizes each object; not a deep dive into any single one |
| NASA Science 3I/ATLAS Facts and FAQs | Official figures directly from NASA | Free, official source | No 3D visualization or side-by-side comparison |
| 'Oumuamua 3D Explorer / 2I/Borisov Interstellar Comet 3D Explorer | Full depth on one specific object's story | Free, in the browser | No three-way comparison across all interstellar objects |
Key published figures
| Figure | Value |
|---|---|
| Orbital eccentricity (3I/ATLAS) | about 6.1 (most extreme of the three) |
| Orbital eccentricity ('Oumuamua) | about 1.2 |
| Orbital eccentricity (Borisov) | about 3.36 |
| 3I/ATLAS closest approach to Earth | about 1.8 AU (270 million km) - no impact risk |

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.
