Visited Solar System, Disturbed Oort Cloud

A star disturbed the comets of the solar system in prehistory,
FECYT - Spanish Foundation for Science and Technology, March 20, 2018.

"About 70,000 years ago, when the human species was already on Earth, a small reddish star approached our solar system and gravitationally disturbed comets and asteroids."

"At a time when modern humans were beginning to leave Africa and the Neanderthals were living on our planet, Scholz's star - named after the German astronomer who discovered it - approached less than a light-year from the Sun. Nowadays it is almost 20 light-years away, but 70,000 years ago it entered the Oort cloud, a reservoir of trans-Neptunian objects located at the confines of the solar system."

"...analyzed for the first time the nearly 340 objects of the solar system with hyperbolic orbits (very open V-shaped, not the typical elliptical), and in doing so they have detected that the trajectory of some of them is influenced by the passage of Scholz´s star."

"Scholz´s star is actually a binary system formed by a small red dwarf, with about 9% of the mass of the Sun, around which a much less bright and smaller brown dwarf orbits. It is likely that our ancestors saw its faint reddish light in the nights of prehistory."
