OSIRIS-REx Sheds Light on Hazardous Asteroid Bennu

The video discusses the challenges in predicting the trajectory of asteroid Bennu due to gravitational and non-gravitational forces, such as the Yarkovsky effect. It highlights the potential impact scenarios if Bennu passes through gravitational keyholes. The Osiris Rex mission significantly improved our understanding of Bennu, reducing uncertainties in its predicted orbit and ruling out several impact scenarios. This research helps in better modeling Bennu's orbital evolution and assessing future risks.
