When to Use the 3I/ATLAS Interstellar Object 3D Explorer - Best Sessions and Limits
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.
Timing questions this 3I/ATLAS comparison does not answer
Two reader tasks fall outside this three-way interstellar timing comparison. First, plotting where 3I/ATLAS sits right now: the object rounded the Sun at perihelion in October 2025 and is already climbing back out of the solar system, so this scene freezes its record eccentricity of about 6.1 for study rather than following its live position. Second, a single-object deep dive: 'Oumuamua's tumbling motion and trajectory anomaly belong on the dedicated 'Oumuamua 3D Explorer, while Borisov's CO-rich coma set against a bound comet belongs on the dedicated 2I/Borisov Interstellar Comet 3D Explorer. Because 3I/ATLAS is a post-perihelion object rather than an upcoming event, the timing question here is comparing its confirmed water outgassing against Borisov and 'Oumuamua, not counting down to a future flyby.
