The asteroid Bennu has been at the centre of scientific discussions recently, especially after researchers analysed surface samples collected by NASA’s OSIRIS-REx mission. While much of the ...
YR4 has a 2.3% chance of hitting Earth in the year 2032. But according to new estimates, it may have an even smaller chance of hitting the moon instead.
NASA spacecraft touched down on the rugged surface of the Bennu asteroid on Tuesday, grabbing a sample of rocks dating back to the birth of our solar system to bring home. The minivan-sized OSIRIS ...
Overall, they write, a Bennu-type asteroid could lead to “severe environmental consequences,” reducing land photosynthesis by 36 percent and marine photosynthesis by 25 percent. That would in ...
Bennu, an asteroid the size of the Empire State Building, has a 1-in-2700 chance of hitting Earth in 2182. 'Fuel-free space travel': NASA engineer claims discovery that defies physics 'Galactic ...
Bennu’s potential collision with Earth is a remote but unsettling possibility, according to a new study. Bennu is about 500 metres wide—taller than the Empire State Building and as wide as ...
The asteroid Bennu is a celestial body with an average diameter of about 560 meters that was discovered in 1999. It is said that it will approach Earth many times over the course of about 200 ...
