Does the Asteroid Bennu Have a Minor Chance of Hitting Earth?
The asteroid Bennu, previously known as 101955 Bennu, is a near-Earth asteroid that has gained significant attention due to its potential risk of impacting Earth. Discovered in 1999, Bennu is estimated to be about 1,600 feet (488 meters) in diameter and has an elongated, peanut-like shape.
Based on current observations and modeling, Bennu has a very small but non-zero chance of impacting Earth in the late 21st century. According to NASA's Sentry impact monitoring system, the probability of Bennu hitting Earth between 2178 and 2290 is approximately 0.037%, or about 1 in 2,700.
While the odds are low, scientists are closely monitoring Bennu's trajectory and conducting research to better understand its potential impact threat. The OSIRIS-REx mission, launched by NASA in 2016, collected samples from Bennu's surface in 2020 and returned them to Earth for analysis. These samples are expected to provide valuable insights into Bennu's composition and structure, which could help scientists refine their predictions about its future trajectory.
It's important to note that the impact threat posed by Bennu is still relatively small compared to other near-Earth objects. NASA and other space agencies are actively tracking thousands of asteroids and comets to assess their potential risks and develop mitigation strategies if necessary.
