A recent survey of astrophysicists has revealed new insights into how long planets typically exist. According to the findings, planets have a wide range of lifespans depending on their size, composition, and the environment of their star systems. Smaller rocky planets may survive for several billion years, while larger gas giants could endure even longer under stable conditions.
Researchers noted that planetary lifetimes are influenced by factors such as stellar evolution, orbital dynamics, and catastrophic events like collisions. Understanding these lifespans helps scientists predict the evolution of planetary systems and the potential for habitability.
This study provides a clearer framework for estimating planetary survival and could guide future astronomical observations. For the space exploration sector and companies investing in exoplanet research, these insights may inform target selection and long-term mission planning, creating opportunities to focus on systems with planets likely to persist over extensive periods.
