The lingering gravitational effects of a star that passed by our solar system some 70,000 years ago can be seen in the movements of dozens of comets today, Gizmodo reports. Astronomers previously found that Scholz’s star, a red dwarf now some 20 light-years away, had once brushed up against the outer limits of our solar system, coming within 0.8 light-years of the sun. Now, scientists have studied the paths of almost 340 comets with exaggerated, hyperbolic orbits, and found that a subset appear to have trajectories that were influenced by the gravity of Scholz’s star, they write in Monthly Notices of the Royal Astronomical Society . Scientists say Scholz’s star is just the most recent example of many to have paid us flying visits in the past.
