this massive asteroid triggered the first-ever notification from the International Asteroid Warning Network (IAWN) on January 29, this year. Over time, subsequent observations and calculations have ...

While we can't be certain, the analysis could not rule out an asteroid with a rocky composition. If this is the case, the researchers calculated, an impact with Earth would release energy between ...

2024 YR4 has a small chance of smacking into the Moon when the asteroid next flies close to Earth in December 2032. "While an Earth impact by 2024 YR4 on December 22, 2032 has now been ruled out," the ...
