A manoeuvre at perihelion was proposed

Hibberd, Crowl and Loeb suggested a technological 3I might use perihelion for a "reverse Solar Oberth" manoeuvre, and Loeb later listed the acceleration among the object's anomalies.

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.
