Bennu is a research area focusing on the study of the asteroid named 101955 Bennu. This asteroid is of particular interest to scientists because it is a near-Earth asteroid that poses a potential impact threat to our planet. Research in this area involves studying the physical properties, composition, orbit, and potential impact hazard of Bennu, as well as exploring potential mitigation strategies in case of a future impact event. The OSIRIS-REx mission, launched in 2016, is a key research project in this area, with the goal of studying and collecting samples from Bennu to gain a better understanding of asteroids and their potential impact on Earth.
