New Evidence Suggests Angry’s CRAZY 3I Atlas Theory Might Be Right!!
- Is the Sunward Anti-Tail of 3I/ATLAS Composed of a Swarm of Objects?
by Avi Loeb
Over the month of November 2025, post-perihelion images of the interstellar object 3I/ATLAS showed a tear-drop shape of its coma with an extension by about an arcminute towards the Sun.
–
During the same period, the JPL Horizons tracking of 3I/ATLAS reported here a non-gravitational acceleration. Its magnitude is a small fraction, of order Δ=0.0002 of the gravitational acceleration from the Sun. In the latest version of JPL Horizons, the non-gravitational acceleration scales inversely with the square of the heliocentric distance (object-Sun separation), exactly as the Sun’s gravitational acceleration. This means that the ratio between the two accelerations remains constant along the orbit of 3I/ATLAS.
–
The dominant component of the non-gravitational acceleration is in the radial direction away from the Sun. A simple way to incorporate it is to consider 3I/ATLAS as accelerating in response to a slightly reduced mass of the Sun, by a fraction of Δ.
–
If 3I/ATLAS is surrounded by a swarm of objects that do not share its non-gravitational acceleration, then these objects will tend to be closer to the Sun relative to 3I/ATLAS, because 3I/ATLAS is pushed away from the Sun relative to the objects through its non-gravitational acceleration.
