NASA Asteroid Bennu: Stunning images show the surface of an asteroid that could hit Earth Science | news



Asteroid Bennu is of particular interest to NASA as it seeks to understand the Earth's potential threat. The imposing asteroid is currently racing through the void about 110 million kilometers from Earth. Despite the enormous distances, the US Space Agency has released the best photos of Bennu photos so far, as it accelerates the exploration of the mysterious surface of the asteroid. NASA's NASIR space probe OSIRIS-REx is the NASIR space probe OSIRIS-REx aims to collect a surface sample of Bennu by 2023.

In front of the daring collection of rock aggregates, NASA's spacecraft enters and exits Bennu's orbit to take detailed snapshots of its surface.

The latest asteroid Bennu images were taken by the spacecraft's MapCam camera on February 25, 201

9.

The asteroid's images include a wide-angle image and two close-up views of a region in Berner's Northern Hemisphere asteroid. The spacecraft was orbiting Bennu, about 1.8 km from the surface of the asteroid.

"The observation plan for this day provided a MapCam image and two PolyCam images every 10 minutes, allowing this combination of context and detail of Bennu's surface . "

NASA researchers have calculated there is one of 2,700 chances that Bennu will collide with Earth between 2175 and 2199.

And although Bennu's asteroid is big enough to destroy a city, one would fortunately, direct impact does not erase life on Earth.

Dante Lauretta, Nasa Osiris-rex chief investigator said, "We're not talking about an asteroid that could destroy Earth.

"We're not near that kind of energy for an impact."

Asteroid Bennu races at around 63,000 miles per hour ( 101,000 kilometers per hour) through space.

The NASA photos are now revealing nearby which threat the Earth might one day experience. [1 9659004] The wide-angle picture (main picture left) shows a 180 m wide area.

There are several rocks, including some boulders, and a regolith hill, mainly made of large stones.

The PolyCam frames are 31 meters wide and the depicted boulder is about the same size as a humpback whale.

As the asteroid moves through space, it also turns and completes a full rotation every 4.3 hours.

NASA's recent research indicates that Bennu's rotation is accelerating.

And this discovery could surprisingly prove to be good news.

This is because Asteroid Bennu may be able to "lose parts of themselves or blow themselves up", thereby reducing their destructive power.
