  • Mars growth was stunted by early giant planetary instability
    on May 7, 2018 at 12:48 pm

    An astrophysics team explains why the growth of Mars was stunted by an orbital instability among the outer solar system's giant planets in a new study on the evolution of the young solar system. The study builds on the widely accepted Nice Model, which invokes a planetary instability to explain many peculiar observed aspects of the outer solar system. The research shows how planet accretion (growth) is halted by the outer solar system instability. […]
