Model predicts destabilization of planetary orbits after Sun loses mass — Nature

Simulations suggest that the orbits of planets in the Solar System could become destabilized within one billion years after the Sun begins to lose mass. Such a scenario could mean the end of the Solar System much earlier than previous estimates had suggested.

Unstable transformation of the Sun

According to Nature, the Sun’s transformation at the end of its existence could be much more unstable than previously believed. The publication presents this conclusion as the result of simulations and points to a possible loss of stability in planetary orbits.

Research and simulations

The Nature article was published on October 6, 2026, as a brief research review. It refers to a scientific paper by K. Batygin, J. Fuller and F. C. Adams, published in 2026 in the journal Astrophysical Journal Letters.

The report discusses a model of future changes to the Sun and their possible impact on the orbital stability of planets. Nature describes this forecast as a possible consequence of the Sun beginning to lose mass.
