Turns out our solar system isn’t as neat and tidy as those school diagrams made it seem. Scientists now think a massive rogue planet or brown dwarf—up to 50 times Jupiter’s mass—once barreled through our early solar system, warping the orbits of the giant planets and leaving everything a bit tilted and stretched. Earth survived the chaos, but the evidence of this ancient cosmic hit-and-run is still written in the stars. Wild, right? #Science #SpaceMystery #SolarSystem
