Passing Stars: Altering Earth's Orbit and Climate

Research suggests that passing stars can alter Earth's orbit, limiting scientists' ability to study the links between past changes in Earth's orbit and climate. Simulations show that a star passing near the solar system can significantly affect Earth's path, shortening the forecasting time span from 77 million years to just 62 million years in the past. The study's findings have implications for understanding ancient climate changes and may impact future predictions of Earth's orbital evolution.
