NASA’s first asteroid sample return mission now knows much more about the material it’ll be collecting in just a few weeks. Be in the know. Sci-News.com. Both surveys had in fact captured the asteroid in the weeks before the flyby, but this slow space rock appeared to move just a tiny amount between images, and was therefore not recognized.

One astronomical unit is the distance from the Sun to Earth, or an average of 93 million miles (150 million kilometers). If an object doesn’t appear to be moving, it’s hard to tell if a point of light is an asteroid or a star.

So if 2019 OK had struck Earth, it could have delivered quite the blow to any city it struck, but would not have been a world-wide event. According to NASA , it was about 45,000 miles from Earth on Thursday.
NASA’s first mission to explore the Trojan asteroids passed a critical milestone and is officially authorized to transition to its next phase. © 2011-2020. "It would have hit with over 30 times the energy of the atomic blast at Hiroshima," astronomer professor Alan Duffy told the Sydney Morning Herald. So the agency plans to launch the Near Earth Object Camera in 2021. OSIRIS-REx is almost ready for touchdown on Bennu. There were several factors that made it hard to detect the asteroid. What is ballot harvesting — and should you hand your ballot to a stranger? It was less than one-fifth of the distance to the moon, making it a very close call in space terms.
An unexpected asteroid named 2019 OK just flew between Earth and the Moon, hammering home the need for continued improvements in both finding and tracking potentially hazardous asteroids.

A huge asteroid flew very close to Earth last week. Its relatively small size, unusual orbit, and fast speed all conspired to make it tough to spot, researchers told the Washington Post. Asteroid 2019 OK came hurtling toward Earth at a speed of nearly 15 miles a second, before flying past. The asteroid, about the size of a large boulder, only became visible a few days ago.
Using several telescopes of the International Scientific Optical Network (ISON), astronomers have captured a series of images of the recently-discovered near-Earth asteroid 2019 OK. As asteroid 2019 OK approached Earth, its position in the sky made it look like it wasn’t moving much until the last few days when its motion finally became apparent in the sky images. Because it’s such a newcomer, there’s still a lot astronomers aren’t sure about, from its orbit to its size, which ranges between 187 to 426 feet (57 to 130 meters) across. Here are 10 things to know about Bennu. Astronomers hunting asteroids and comets close to our planet — near-Earth objects or NEOs — watch for movement against a background of stars.

For reference, the asteroid purported to have killed the dinosaurs 66 million years ago was about 10 miles (16 km) across, if not larger, while the meteor that flew over Chelyabinsk, Russia in 2013 was only 66 feet (20 m) across. A deepfake bot is being used to “undress” underage girls.
