10x Sunward Glow Extension

The glow around 3I/ATLAS extends 10 times farther toward the Sun than its width - completely opposite to normal cometary behavior where tails point away from the Sun.

Anomalously Massive Object

With a mass exceeding 33 billion tons and diameter >5km, 3I/ATLAS is 3-5 orders of magnitude more massive than previous interstellar objects.

Lack of Non-Gravitational Acceleration

Despite evidence of mass loss, shows minimal non-gravitational acceleration (<15 m/day²) - inconsistent with typical cometary behavior.

Statistical Discovery Impossibility

We should have found ~100,000 objects like 'Oumuamua before finding one like 3I/ATLAS, yet only 2 previous interstellar objects were detected.

CO₂-Dominant Composition

Plume is 87% carbon dioxide, 9% carbon monoxide, 4% water - unlike typical water-rich comets.
