When to Use the 3I/ATLAS Interstellar Object 3D Explorer - Best Sessions and Limits

Last reviewed: 2026-08-12

Open the 3I/ATLAS Interstellar Object 3D Explorer when you want to see how 3I/ATLAS's real orbit and activity compare against the two interstellar objects discovered before it - not to track 3I/ATLAS's current position (it passed perihelion in October 2025).

A three-way comparison, not a live tracker

A session starts on 3I/ATLAS (the default) to see its record eccentricity of about 6.1 and its confirmed water outgassing, then slides to Borisov (eccentricity about 3.36, CO-rich coma) and 'Oumuamua (eccentricity about 1.2, no coma at all) - while the comparison table stays fixed, ranking all three side by side.

Sessions this explorer does not fit

Sessions this page does not fit are tracking 3I/ATLAS's live position (it is now leaving the solar system) or a deep dive into one single object's own story - 'Oumuamua's tumbling motion and trajectory anomaly are on the dedicated 'Oumuamua 3D Explorer, and Borisov's coma-composition contrast against a bound comet is on the dedicated 2I/Borisov Interstellar Comet 3D Explorer. Walk through the controls in the step-by-step guide.
