Caltech study warns of accelerated solar system instability

New research published in The Astrophysical Journal Letters by scientists from Caltech suggests the solar system may lose its stability and configuration much sooner than previous models predicted. The study indicates that the evolution of the Sun will drastically alter the cosmic neighborhood, potentially dismantling the outer solar system within billions of years.

As the Sun exhausts its hydrogen fuel, it is expected to expand into a red giant. This process will likely consume Mercury and Venus, while Earth may face a loss of habitability due to orbital changes and proximity to the expanding star.

Furthermore, the research highlights that the Sun's transition into a white dwarf will involve turbulent mass loss. These violent, stochastic ejections could trigger gravitational chaos, destabilizing the orbits of giant planets like Jupiter and Saturn and potentially hurling them into interstellar space.
