An astronomer has captured “extraordinary” footage of an asteroid that made an “extremely close” approach to the Earth on Thursday.
The space rock, known as 2023 BU, zoomed over the southern tip of South America yesterday, while it was only around 2,200 miles above the surface of the Earth.
This is one of the closest approaches of an near-Earth object ever recorded. Data from NASA’s Center for Near Earth Object Studies showed that the flyby of 2023 BU was the fourth-nearest of more than 35,000 past and future Earth close approaches in the 300-year period from 1900 to 2200.

While artificial intelligence systems might make lives exponentially easier, they could also have a sinister side effect — making us go extinct. That’s right, researchers are deeming rogue AI an “existential threat to humanity” that needs to be regulated like nuclear weapons if we are to survive.
Please join the Project on Nuclear Issues for a book launch event, featuring “The Fragile Balance of Terror: Deterrence in the Nuclear Age.”
In The Fragile Balance of Terror, edited by Vipin Narang and Scott Sagan, the foremost experts on nuclear policy and strategy offer insight into an era rife with more nuclear powers. Some of these new powers suffer domestic instability, others are led by pathological personalist dictators, and many are situated in highly unstable regions of the world—a volatile mix of variables. The increasing fragility of deterrence in the twenty-first century is created by a confluence of forces: military technologies that create vulnerable arsenals, a novel information ecosystem that rapidly transmits both information and misinformation, nuclear rivalries that include three or more nuclear powers, and dictatorial decision making that encourages rash choices. The nuclear threats posed by India, Pakistan, Iran, and North Korea are thus fraught with danger.

Paula and Bill Lishman spent many winters in a poorly-insulated A-frame cabin before realizing they needed to go underground to use the earth’s energy to stay warm, so they knocked the top off a hill, dropped in ferro-cement domes, and covered it up again with dirt.
Thanks to skylights cut into every dome and the white-powdered marble that covers the interior, their earth-sheltered home is naturally well-lit despite being below the frost line.
When Japan’s Hayabusa mission traveled to asteroid Itokawa, it collected samples. These successfully reached Earth in 2010.
Near Earth asteroid Itokawa is a rubble pile that formed more than four billion years ago, a new study found. So, these asteroids might be resilient to demise.
