A new study published in the Monthly Notices of the Royal Astronomical Society proposes that the Sun might have consumed a super-Earth — a planet much larger than Earth — during its early development. This idea could help explain some long-standing mysteries about the Solar System, particularly strange features observed in the Sun’s structure and chemical makeup. Scientists have noticed that the Sun has less lithium on its surface than expected, and its internal sound speed profile — studied through a technique called heliosismology — doesn’t match standard models of how stars evolve. These anomalies have puzzled researchers for years, as they don’t fit with the usual understanding of how stars like the Sun form and change over time. To explain these oddities, researchers suggest that the Sun may have swallowed a massive, rocky planet, about five to ten times the mass of Earth. Computer models show that such a planet, if it formed close to the Sun and then migrated inward, could have been consumed without causing major disturbances to the star. This event might also explain why there is no super-Earth in our immediate solar neighborhood, even though such planets are common around other stars. Although the physical remains of the swallowed planet would likely have been destroyed by the Sun’s intense heat and pressure, the study suggests that the Sun’s internal structure and chemical composition could still hold indirect evidence of the event. These "fingerprints" might be detectable through seismological data. If confirmed, this discovery could reshape our understanding of the Sun’s early history and the processes that shaped our Solar System.
