@cosmoknowledge: The Sun’s final chapters could throw the outer solar system into chaos. A new study suggests that uneven bursts of escaping gas could give the aging Sun small kicks, disrupting the giant planets’ orbits. Some simulations sent planets into space, while others made Uranus and Neptune swap orbital order. These are possible outcomes, not a certain forecast. The study points to a much shorter survival time for the outer planets after the Sun’s death, not an earlier death for the Sun itself.
