The Sun may have swallowed a massive “Super-Earth” planet containing five to 10 times the mass of Earth during the early formation of the solar system, according to new research published in the Monthly Notices of the Royal Astronomical Society. Led by Prof. Mutlu Yildiz of Ege University in Turkey, the study offers a potential explanation for why our solar system lacks a Super-Earth type planet, which remains a common feature in other star systems across the galaxy.
Uncovering the Solar System’s Missing Planet
Researchers investigating discrepancies between standard solar evolution models and recent observational data identified two major clues pointing to an ancient planetary ingestion. The study highlights subtle alterations in the Sun’s internal structure alongside an unexpected scarcity of lithium on the star’s surface. According to the findings cited by BGR, the Sun has lost considerably more lithium than theoretical models predict.
Simulations tracking the growth of the Sun’s outer layers indicate that the kinetic impact of swallowing a Super-Earth would force the majority of surface lithium deep into the stellar interior. Once pushed into these deeper layers, the element burns away much faster than it would near the surface. This mechanical mixing process resolves a longstanding puzzle that has occupied astronomers for years regarding our stellar neighbor’s unusual chemical composition.
Chemical Fingerprints Left by Planetary Ingestion
Even though the Sun operates as an intensely hot ball of plasma, any massive planetary body crossing its outer envelope would theoretically leave behind detectable chemical markers before melting completely. As the candidate Super-Earth plunged into the star, its mass disrupted the convective envelope and altered the star’s internal distribution of elements. Researchers stress that while these computer simulations present a compelling narrative for the solar system’s violent youth, absolute proof remains out of reach.
Confirming the hypothesis definitively would require future technological breakthroughs capable of reconstructing detailed billions-of-years-old celestial mechanics. For now, the computational models provide the most rigorous framework available to explain how our stellar neighborhood lost a massive planetary member to the Sun’s gravitational pull.

Common Questions Regarding the Sun’s Lost Planet
Did the Sun actually swallow a planet?
Current computational models led by Prof. Mutlu Yildiz suggest the Sun likely pulled in and consumed a massive Super-Earth during the formative stages of the solar system.
What evidence supports this planetary ingestion theory?
Researchers discovered an unusual scarcity of surface lithium on the Sun and subtle inconsistencies in its internal structure when compared against standard stellar evolution models.
Can scientists prove this event happened?
The findings remain grounded in theoretical computer simulations. Absolute verification will require future technological capabilities that can reconstruct ancient cosmic events in high detail.
