Comets still disturbed by star's flyby 70,000 yrs ago: Study
Spain and UK-based astronomers have found that the gravitational effects of a star that came within 0.6 light-years to our solar system 70,000 years ago continue to exist. The researchers studied 340 comets and asteroids having V-shaped hyperbolic orbits and found some of the trajectories are still influenced by the passage of Scholz's star, which is currently 20 light-years away.
