And while conventional models suggest the Sun will meet its final demise when it grows into a red giant and collapses to form a white dwarf some six billion years from now, the fate of its surviving planets remains a subject of debate. Researchers had previously suggested that any planets in the star's vicinity, including the Earth, will be swallowed up, while the more distant gas giants remain largely intact long after the Sun's demise. But a [new paper]() published in *The Astrophysical Journal Letters* paints an even more dire picture. The team led by California Institute of Technology astrophysicist Konstantin Batygin argues that even these distant objects may not make it across the one billion-year mark after the Sun collapses into a white dwarf, an extremely dense husk of a stellar core. They suggest that even before the Sun turns into a white dwarf, there's a high chance that the orbits of the various planets will cross each other — a "dynamical instability" that could doom the entire planetary system much sooner than previously thought. The latest findings suggest that the real chaos could kick off as little as a billion years after the Sun turns into a white dwarf. To reach that conclusion, the scientists modeled the movements of the planets as the Sun went through its final stages over billions of years using a supercomputer. They suggest that the Sun's transition into a white dwarf could be marked by "stochastic kicks," in which it will violently eject mass. In other words, our star's death throes could be sudden and unpredictable, dooming the planets it formed billions of years previously by disrupting their orbits and triggering their ultimately fatal "violent scattering." "Newton, contemplating the drifting orbits of Jupiter and Saturn, suspected that the planetary order was mortal, and three centuries of celestial mechanics — from the classical invariability theorems to billion-year numerical integrations — have progressively deferred that verdict, most recently to timescales far beyond the age of the Universe," the paper reads. "Our results return the solar system’s dissolution to astrophysically familiar territory, and relocate its cause: not the slow seep of chaos, nor the chance encounter with a passing star, but the Sun itself, which in dying does not merely enlarge the planetary system it built — it shakes it, and more often than not, spills it," it continues. **More on the Sun's death:** [*Scientist Reveals Plan to Save Earth From Destruction by the Sun*]() ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
