The interstellar comet 3I/ATLAS is now thought to be 10 to 12 billion years old, meaning it was already drifting between the stars for more than twice the age of the Sun before our solar system existed.
The newest estimate for interstellar comet 3I/ATLAS changes the scale of the object. It is not just older than the solar system. If the interpretation...
