What Is 3I/ATLAS Going To Do On December 15th?

December 15th, 2025. Interstellar object 3I/Atlas reaches Earth at 170 million miles — closer than any confirmed visitor from another star system.
It weighs 33 billion tons. We know because despite active outgassing, its trajectory follows pure gravity with impossible precision. The jets can't move it.

It arrived 5 degrees from our ecliptic plane — 1 in 500 odds. Threaded past Venus, Mars, and Jupiter when all three were positioned correctly — 1 in 20,000. Reached perihelion October 29th when Earth was directly behind the Sun, hidden for three weeks during peak activity.

Thermal patterns pulse in cycles. Nickel emissions without iron. Rotation maintains stable solar orientation. And now: structured radio signals. Timed. Directed.

December 15th isn't just closest approach. It's our final window before 3I/Atlas disappears into interstellar space forever.

Hubble and Webb are aimed. The data keeps getting stranger.

Rarest natural object in a thousand years? Or something that wakes up near inhabited systems?

The answer is coming.
