A new study using improved models of tidal dissipation and solar mass loss suggests Earth may survive the Sun's expansion into a red giant, though outcomes remain uncertain; Mercury and Venus face destruction, Mars could migrate outward, and the outer planets’ futures vary as the Sun evolves.
A new study using refined tidal models and revised solar mass-loss estimates suggests Earth might avoid engulfment by the Sun during its red-giant and asymptotic giant branch phases, potentially widening its orbit enough to stay outside the Sun’s maximum size (Mars may also survive; Mercury and Venus likely wouldn’t). However, habitability would end long before then due to intense solar radiation, and the outcome depends on late-stage mass loss, a quantity still hard to predict, warranting future observations.
A recent study explores the formation mechanisms of binary planets, which are two large planetary bodies orbiting each other. The study suggests that tidal dissipation, or the energy shared between two planetary bodies as they orbit close to each other, could be a key factor in the formation of binary planets. Binary planets are not present in our Solar System, but their existence could open up new possibilities for habitable satellites orbiting giant planets. Understanding binary planets could also provide insights into the formation and evolution of exoplanets and their systems.
