New research reveals a past cosmic event where Earth's orbit was significantly altered by a close encounter with a passing star, potentially causing dramatic climate changes. This incident, occurring around 56 million years ago, might explain the substantial warming Earth experienced during the Paleocene-Eocene Thermal Maximum. Scientists Nathan Kaib and Sean Raymond, utilizing simulations, suggest such stellar encounters could disrupt planetary orbits, impacting Earth's climate. This hypothesis highlights the need to consider galactic dynamics in understanding Earth's climate history. The study is published in The Astrophysical Journal Letters.
