The new interstellar comet's official name is 3I/ATLAS. It's officially the third known interstellar object to pass through our solar system, and it poses no threat to Earth.

On Wednesday, the comet made its closest approach to our sun and on Saturday, October 12 at 11:39 a.m. it will be just 43,911,824 miles from Earth (its closest pass).

The comet, which will be visible to the naked eye, orbits the sun roughly once every 80,000 years—the last time it passed Earth humans were just migrating out of Africa.
