I'm curious about what, if any, gravitational effects this would've had on the earth? Seems like its a relatively small star and it was so far away that I'm guessing any pull would've been negligible.
> The effect of a passing star on the Oort Cloud is a function of the star's mass, speed and proximity. The worst case scenario for stirring up comets would be a slow-moving, massive star that came close to the Sun.
> Scholz's star came relatively close, but the binary system (the red dwarf and its brown dwarf companion) has a low mass and it was speeding by. These factors conspired to make its effect on the Oort Cloud very small.
