NASA: Asteroid longer than FIVE double decker busses to scrape Earth TOMORROW | Science | News |

For reference, the Lockheed SR-71 Blackbird, the fastest jet ever built, could not even reach New York from London in an hour.

One AU is the distance between the Earth and the Sun (149,598,000 km), so 0.037 AU is 5,535,121 km.

While this may seem like a sizeable distance, it is close enough for NASA to sit up and take notice.

The US-based space agency have classed 2019 WR3 as a Near Earth Object (NEO) and allow the space agency to study the history of our solar system.

NASA's daring asteroid mission is trying to find a landing spot on Bennu - CNET

NASA is days away from choosing a sample site for its intrepid spacecraft's sample collection operation, the agency announced on Wednesday. It hasn't been an easy process. In July, NASA narrowed the options down to four sites with bird-themed names: Nightingale, Kingfisher, Osprey and Sandpiper.

Osiris-Rex has been performing reconnaissance flybys of the sites, snagging high-resolution images and giving its team plenty of food for thought.

There's Something Weird About the Craters of Asteroid Ryugu | Space

The Japanese mission Hayabusa2 just bid farewell to the asteroid the probe spent a year and a half studying, and scientists have now announced some intriguing trends they noticed in the spacecraft's photos.

Those trends had to do with the craters dotting the surface of the asteroid, dubbed Ryugu . The team used 340 different images of the space rock's surface and identified a total of 77 craters scattered over Ryugu, each measuring at least 66 feet (20 meters) across. But those pockmarks aren't distributed as evenly across the surface as the scientists might have expected, the researchers explained in a new paper.

And here's another article:

A Spacecraft Will Follow NASA's Asteroid-Smashing Mission to Measure the Effects of the

The Hera mission is a companion to NASA’s Double Asteroid Redirection Test (DART) mission , scheduled to launch in July 2021. The spacecraft will travel for more than a year to the double asteroid Didymos, a 2,560-foot diameter main body orbited by a 525-foot satellite moonlet called Didymos B or Didymoon. DART will slam into the Didymoon, altering the object’s speed by a fraction of one percent. Scientists project the impact will be enough to change its orbit by several

While observations from Earth can somewhat assess DART’s success at altering Didymoon’s orbit, a closer vantage point will give a much more detailed picture. That’s where the Hera mission comes in. Mike Wall at Space.com reports the probe will likely launch in 2023 or 2024, taking two years to reach the asteroid. Upon arrival, Hera will circle Didymoon, mapping its surface, measuring its mass and determining the effect of DART on its orbit.

US meteorite adds to origins mystery - BBC News

In January 2018, a falling meteorite created a bright fireball that arced over the outskirts of Detroit, Michigan, followed by loud sonic booms.

The visitor not only dropped a slew of meteorites over the snow-covered ground, it also provided information about its extra-terrestrial source.

Although tens of thousands of meteorites have been recovered by humans, scientists have only been able to trace the orbits of a small number. Most of these have been calculated in the last decade.
