Interstellar Object Influenced Planetary Orbits
A new theory suggests that an interstellar object, with a mass between 2 to 50 times that of Jupiter, may have passed through the Solar System and influenced the orbits of the planets. This theory, proposed by scientists led by Garett Brown from the University of Toronto, posits that such a visitor could explain the eccentricities of the gas giants' orbits better than current models. The study indicates a 1 in 100 chance that this event shaped the planetary orbits we observe today, offering a plausible alternative to existing theories of planetary migration.
