Disturbing Encounter 70,000 Years Ago Shifted the Orbits of Comets In the Outer Solar System.

A star disturbed the comets of the solar system 70000 years ago

It also included that the red dwarf star had a mass of 9% of solar mass while its companion, the brown dwarf had a 6% solar mass. The close fly-by of this star 70,000 years ago did not disturb all the hyperbolic objects of the solar system, only those that were closest to it at that time.

 From article, (A star disturbed the comets of the solar system 70000 years ago.The astronomers came to this conclusion by measuring the motion and velocity of Scholz's star - which zooms through space with a smaller companion, a brown dwarf or "failed star" - and extrapolating backward in time. 

Now, two astronomers from the Complutense University of Madrid, the brothers Carlos and Raúl de la Fuente Marcos, together with the researcher Sverre J. Aarseth of the University of Cambridge (United Kingdom), have analyzed for the first time almost 340 solar system objects with hyperbolic orbits (very open V-shaped, rather than elliptical) They have concluded that the trajectories of some of these were influenced by the passage of Scholz's star. That means its trip would have taken it through the Oort Cloud, the swarm of icy objects that surrounds the Solar System, and its visit wouldn't have gone unnoticed by the locals. - Carlos de la Fuente Marcos, Complutense University of Madrid.

A computer simulation was used to calculate the positions in space of the objects from where they originated and they found that some of the hyperbolic objects towards the direction of Gemini Constellation show favorable results. A statistically significant number of them, 36, have radiants-or the points from which they seem to radiate from the sky-pointing back towards the constellation Gemini. Normally, the radiants of those objects would be evenly distributed across the sky if they randomly came out of the Oort cloud. Statistical analysis showed that some of these distant comets featured trajectories that were very likely to have been influenced by Scholz's Star. Or, they could be natives of our Solar System, originally bound to an elliptical orbit, but cast into a hyperbolic orbit by a close encounter with one of the planets, or the Sun. "It could be a coincidence, but it is unlikely that both location and time are compatible", says De la Fuente Marcos. It's estimated that a star passes through the Oort Cloud every 100,000 years.
