Near-Earth asteroid Bennu has a slim chance of colliding with Earth in 2182. If it does, the impact could trigger a global winter that affects our planet for years.
The rocky object called Bennu is classified as a near-Earth asteroid, currently making its closest approach to Earth every six years at about 186,000 miles (299,000 km) away. So what would happen ...
This mosaic image shows the asteroid Bennu, composed of 12 PolyCam images collected on December 2, 2018 by the OSIRIS-REx spacecraft from a range of 15 miles (24 km).
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024 [update] , all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors .
A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7 percent chance of striking Earth in 2029. Further observations ruled out an impact. "City killer ...
This mosaic image of asteroid Bennu, was taken on December 2, 2018 by the OSIRIS-REx spacecraft from a range of 15 miles. Organic samples returned from Bennu contain the building blocks of life on ...
The asteroid was given the provisional designation 1999 RQ 36 and classified as a near-Earth asteroid. [26] Bennu was observed extensively by the Arecibo Observatory and the Goldstone Deep Space Network using radar imaging as Bennu closely approached Earth on 23 September 1999. [27] [12]
While still an extremely low possibility, asteroid 2024 YR4's impact probability with Earth has increased from about 1% to a 2.3% chance on Dec. 22, 2032. As we observe the asteroid more, the ...
