An interstellar visitor may have changed the course of 4 solar system planets, study suggests
A new study suggests that a planet-sized object may have passed through our solar system around 4 billion years ago, altering the orbits of the four outer planets—Jupiter, Saturn, Uranus, and Neptune. This flyby could explain why their orbits are slightly tilted and elliptical. Using computer simulations, researchers found that objects ranging from two to 50 times the mass of Jupiter could have caused these … Continue reading An interstellar visitor may have changed the course of 4 solar system planets, study suggests
