The Osiris-Rex mission will be back from asteroid Bennu in early 2023. Does Bennu pose an impact risk to Earth? It has a cumulative 1-in-1,800 chance of impacting Earth All other colors (green, yellow, orange, and red) represent their respective Torino scale. Bennu has been measured by planetary radar and is roughly spherical with an equatorial bulge. If a similar-sized object were to hit Earth, it would be devastating. Sep. 9, 2020 A new study posits that the major particle ejections off the near-Earth asteroid Bennu may be the consequence of impacts by small, sand-sized particles called meteoroids onto its Heres what it means for our future. The color of the table row gives a rough interpretation of the severity of the threat. The impact might send dust and debris into the sky, creating a haze that would cool the atmosphere and absorb sunlight, enveloping the entire planet in darkness. This undated image made available by NASA shows the asteroid Bennu from the OSIRIS-REx spacecraft. The photo was released in December 2020 as an example of one of the largest, nearly complete Einstein rings ever seen.

The photo was released in December 2020 as an example of one of the largest, nearly complete Einstein rings ever seen. The Osiris-Rex mission will be back from asteroid Bennu in early 2023. White or gray colors indicate a Torino scale of 0 or undefined. Does Bennu, the asteroid that will be studied by the OSIRIS-ReX spacecraft, pose an impact risk to Earth? This undated image made available by NASA shows the asteroid Bennu from the OSIRIS-REx spacecraft. Bennu has been measured by planetary radar and is roughly spherical with an equatorial bulge. Sep. 9, 2020 A new study posits that the major particle ejections off the near-Earth asteroid Bennu may be the consequence of impacts by small, sand-sized particles called meteoroids onto its Its average diameter is about 1,614 feet (492 meters). OSIRIS-REx was launched in 2016 and is currently mapping the asteroid Bennu, which was chosen for this mission because of its size, Bennu has been measured by planetary radar and is roughly spherical with an equatorial bulge. A spacecraft that must ultimately crash to succeed was launched late on Tuesday from California on a NASA mission to demonstrate the world's first planetary defense system, designed to deflect an asteroid from a potential doomsday collision with Earth. OSIRIS-REx was launched in 2016 and is currently mapping the asteroid Bennu, which was chosen for this mission because of its size, composition, and proximity. 101955 Bennu (provisional designation 1999 RQ 36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. All other colors (green, yellow, orange, and red) represent their respective Torino scale. Does Bennu, the asteroid that will be studied by the OSIRIS-ReX spacecraft, pose an impact risk to Earth? This undated image made available by NASA shows the asteroid Bennu from the OSIRIS-REx spacecraft. It is a potentially hazardous object that is listed on the Sentry Risk Table and tied for the highest cumulative rating on the Palermo Technical Impact Hazard Scale.
