Interstellar Visitor 3I/ATLAS Shrinks Mysteriously Before Earth Approach
10 Nov, 2025
Summary
- 3I/ATLAS has shed 13% of its material after passing the sun
- Physicist Avi Loeb warns it could be an alien mothership in disguise
- 3I/ATLAS has displayed 10 strange anomalies, suggesting artificial origin
On November 10, 2025, new images have revealed that the interstellar visitor 3I/ATLAS has mysteriously shrunk in size in the weeks leading up to its closest approach to Earth on December 19. NASA recently calculated that 3I/ATLAS has shed 13% of its material after passing the sun last month.
Harvard Professor Avi Loeb, who has been analyzing the object since the summer, noted that this sudden shrinkage was directly tied to a noticeable change in the interstellar object's course as it moved closer to the sun. Loeb has previously warned that contact with 3I/ATLAS has the makings of a 'black swan event,' meaning this massive space object could be an alien mothership trying to disguise itself as a space rock for an unknown purpose.
