Earth may avoid being swallowed by the Sun, new study suggests
Updated models indicate Earth could drift outward as the Sun loses mass, though some researchers still expect engulfment.

The article discusses a new study on the distant future of the Sun and Earth. It contrasts the study’s more optimistic conclusion with earlier research that said Earth would be engulfed during the Sun’s red giant phase.
A new study suggests Earth may survive the Sun’s red giant phase by drifting outward as the star loses mass. The result conflicts with earlier research that predicted Earth would still be engulfed.
The study argues that updated models of how aging stars interact with their planets make the inward pull toward the expanding Sun weaker than older models predicted. That could allow Earth to move outward fast enough to avoid being swallowed, even though Mercury and Venus would still be engulfed.
The article notes that this remains an open scientific question, and that earlier studies reached the opposite conclusion. It also points out that Earth’s ultimate fate depends on how much mass the Sun loses as it evolves.
