3I-ATLAS comet anomalies have astronomers buzzing as the third confirmed interstellar object makes its closest Earth pass at 270 million km today before heading out forever. Discovered early 2025 by ATLAS survey, this hyperbolic wanderer—on a retrograde, near-perpendicular orbit—shows bizarre traits that challenge comet norms, with Harvard’s Avi Loeb listing 15 oddities.
NASA’s ongoing observations
NASA continues tracking C/2025 N1 (3I/ATLAS) via telescopes 20cm+ as it swings past Jupiter, Mars, Earth, Venus and Sun without close Earth risk. Unlike bound Oort Cloud comets, its unbound path confirms extrasolar origin, akin to ‘Oumuamua and Borisov.
Loeb’s 15 anomalies sparking debate
Avi Loeb highlights peculiarities defying natural comet models:
-
Jet points toward Sun, not away
-
Tightly collimated, stable jet
-
Retrograde orbit opposite ecliptic
-
Multiple planetary flybys
-
No dust coma, odd brightness
-
Active far from Sun
-
Nickel without iron, missing volatiles
-
Jets unexplained by ice sublimation
This rare cluster prompts Loeb to question artificial origins, echoing ‘Oumuamua theories.
