The push peaks a month after perihelion, with the activity
JPL's orbit solution 55 fits a radial acceleration of (4.62 ± 0.48) × 10^-8 au per day squared at 1 au, with transverse and normal terms, peaking 28.5 ± 9.2 days after perihelion, when the comet was most active.
What it means
Openunchanged
Answer this evidence bears onGas escaping from the nucleus, as on any active comet
Supports3 for, none against
Still possibleunchanged
What it implies
- The push follows the comet's activity, as outgassing does.For the key question: What pushes 3I/ATLAS off a purely gravitational path?

Details
JPL solution 55 was made to support JWST program 13145 and uses observations to 16 October 2026. Compare the next solutions: an acceleration that stays at zero far out on the outbound leg supports outgassing; one that persists would not.
