Submission + - SPAM: A Star Grazed Our Solar System 70,000 Years Ago, and Early Humans Likely Saw It.

schwit1 writes: Some distant objects in our solar system bear the gravitational imprint of a small stars close flyby 70,000 years ago, when modern humans were already walking the Earth, a new study suggests.

In 2015, a team of researchers announced that a red dwarf called Scholzs star apparently grazed the solar system 70,000 years ago, coming closer than 1 light-year to the sun. For perspective, the suns nearest stellar neighbor these days, Proxima Centauri, lies about 4.2 light-years away. The astronomers came to this conclusion by measuring the motion and velocity of Scholzs star — which zooms through space with a smaller companion, a brown dwarf or "failed star" — and extrapolating backward in time.

The unfacts, did we have them, are too imprecisely few to warrant our certitude.
