New Modeling Suggests the Sun Consumed an Ancient Super-Earth
New calculations from a paper published in a Royal Astronomical Society journal in September 2026 indicate that an infant sun may have swallowed a super-Earth with roughly five to ten times the mass of our planet. This event could explain longstanding anomalies in the sun, specifically discrepancies in internal sound wave speeds and low surface lithium levels. While other star systems frequently contain super-Earths, our solar system lacks them entirely. However, astronomers emphasize that this scenario has not yet been confirmed through direct observation.
Why it matters
The newly examined modeling addresses why our solar system lacks a category of planet that is common around other stars. Researchers used computational scenarios to test whether planetary engulfment leaves lasting chemical and physical traces inside stellar interiors.
What is confirmed
- A study published in a Royal Astronomical Society journal in September 2026 calculates that the sun may have swallowed a planet with five to ten times the mass of Earth.
- Astronomers postulate that the original innermost planet crashed into the sun and was destroyed, leaving deviations in solar features.
- Researchers used simulation to determine that this engulfment scenario accounts for both internal sound wave speed discrepancies and low surface lithium levels in the sun.
Still unconfirmed
- Direct observational proof confirming that the sun swallowed a super-Earth has been obtained.

Study Suggests Young Sun Swallowed a Super-Earth
Astronomers propose that the sun consumed a massive super-Earth during its early formation, potentially resolving longstanding discrepancies in standard solar models. Researchers from Ege University in Turkey used stellar evolution software to simulate planet engulfment, finding that the consumption of a body with a mass of five to ten times that of Earth matches both surface lithium levels and internal sound wave speeds. This event could explain why our solar system lacks a super-Earth, a planet type common in other star systems. Ancient meteorites also reveal a powerful magnetic field that may have fed the growing sun.
Why it matters
Standard solar models have long exhibited discrepancies between predicted and observed data regarding solar lithium levels and internal sound wave speeds. Investigating whether the sun acted as a planet killer provides a physical mechanism for these anomalies. Additionally, this theory addresses the notable absence of super-Earths in our solar system compared to other stellar systems.
What is confirmed
- A study published in September 2026 in the Monthly Notices of the Royal Astronomical Society suggests the sun swallowed a super-Earth with a mass of 5 to 10 times that of Earth during its youth.
- Mutlu Yildiz and a research team at Ege University in Turkey simulated planetary engulfment scenarios and compared them against observational data.
- Standard solar model predictions conflict with actual observations regarding solar surface lithium content and internal sound wave speeds.
Still unconfirmed
- The missing super-Earth hypothesis definitively explains why our solar system lacks a planet type that is common in other stellar systems.
What to watch next
- Further empirical verification of the planetary engulfment hypothesis through advanced stellar modeling and seismology
- Additional data connecting ancient meteorite magnetic fields to the early solar system formation process
