Description

Post-perihelion image of the interstellar object 3I/ATLAS, taken on November 5, 2025 by the R. Naves Observatory, shows a fuzzy ball of light with no clear cometary tail.

Here's the Loeb writeup about it: https://avi-loeb.medium.com/no-clear-cometary-tail-in-post-perihelion…

Loeb estimates that the object would have needed to lose approximately 13% of its mass to account for the non gravitational acceleration (based on a cometary model).

And here's a fun video from the Angry Astronaut where he calculated that the non gravitational acceleration witnessed, based on estimated mass, would require approximately 9 SpaceX Starship engines worth of thrust applied for an *entire day:* https://youtu.be/dUWf4Z3L41I
