Briefings

Recent modeling indicates the solar system's orbits will become destabilized within one billion years as the Sun sheds mass, potentially triggering a catastrophic collapse. This finding challenges previous estimates of the system's stability timeline.

Key points

• Models predict solar system orbital destabilization occurring within one billion years due to solar mass loss.
• The specific date of this destabilization event is not yet determined by current models.

Context

A new study suggests the solar system's stability timeline is shorter than previously estimated, with orbits becoming unstable as the Sun loses mass over the coming billion years.

Limitations

The evidence is limited to a single modeling study published in October 2026. The exact date of destabilization remains unknown, and the study does not account for all potential instability mechanisms.
