3I/ATLAS: New Non‑Gravitational Acceleration Update & Jupiter Flyby Anomaly

Описание: New data on the interstellar object 3I/ATLAS reveal major revisions to its non‑gravitational acceleration and a strange near‑match with Jupiter’s Hill radius.
In this video, we break down:
What “non‑gravitational acceleration” means for 3I/ATLAS and why NASA’s JPL Horizons keeps updating its value A1.
How the reported radial acceleration dropped by orders of magnitude as new models were applied.
Why the latest JPL model assumes a 1/r² dependence (CO2‑driven sublimation) and how this differs from traditional water‑ice comet models.
The predicted March 16, 2026 close approach to Jupiter, and why the perijove distance being so close to Jupiter’s Hill radius is statistically remarkable.
How different radial brightness profiles (from about 1/r² up to a very steep ~1/r^7.5 inside ~2 AU) tie luminosity to mass loss and thrust.
Why some researchers argue the current JPL model may underestimate a steeper near‑perihelion acceleration.
What upcoming astrometric data from missions like Juno, Juice, and Psyche might reveal about the true trajectory.
Why a precise match between perijove and the Hill radius could be considered a potential technosignature scenario.
