NASA’s OSIRIS-REx asteroid probe has spotted the asteroid Bennu flinging pieces of its own surface into space. These “particle ejection events” happen all the time, … ...

Bennu was discovered in 1999 and is believed to be part of a larger asteroid that collided with another space rock. It’s about one-third of a mile wide and is roughly the height of the Empire ...

The impact of a tiny body on the asteroid Bennu caused a rock slide that revealed the surface properties of rock-pile asteroids. When you purchase through links on our site, we may earn an ...

"We have over a 1,000 particles that are greater than half-a-millimeter, 28 particles that are greater than a centimeter, and the biggest particle is 3.5 centimeters," said University of Arizona's ...

For decades, scientists have suspected that a fifth fundamental force might exist. Unlike the four already identified ...

Bennu, discovered in 1999, is a carbon-rich asteroid that is almost black in color. It is about 1,600 feet wide. That compares to the Empire State Building, which is 1,454 feet tall including the ...

NASA says Bennu asteroid sample shows evidence of water, carbon 00:24. Rocks and soil collected from the asteroid Bennu and brought back to Earth last month by NASA's OSIRIS-REx probe are rich in ...

Bennu orbits at an average speed of 63,000 miles per hour. Once close to Earth, it takes around 1.2 years to orbit the sun fully, and rotates once every 4.3 hours.

Among them, the near-Earth asteroid, known as Bennu, contains a surprising reservoir of a mineral called magnesium phosphate. These bright-white particles sprinkled in a sea of Bennu's dark rocks ...

Dante Lauretta didn’t expect the surface of the asteroid to be, as he puts it, “fluffy.” As NASA’s OSIRIS-REx spacecraft descended toward asteroid Bennu to grab a sample of its surface ...

Near-Earth asteroid Bennu has a slim chance of colliding with Earth in 2182. If it does, the impact could trigger a global ...

Bennu is a roughly 0.3-mile-wide (500 meters) asteroid that orbits in near-Earth space. Scientists suspect it’s a chunk of a larger asteroid that broke off due to a collision farther out.
