"Close Encounters: 5 Building-Size Asteroids Set to Pass Earth"

A building-sized asteroid, 2024 CJ8, will pass by Earth tonight, coming within 4.1 million miles of the planet, but poses no threat. NASA classifies asteroids larger than 492.126 feet and within 4.6 million miles as "potentially hazardous," but this one doesn't meet the size requirement. More than 1.3 million asteroids are estimated in the solar system, and NASA has been increasing efforts to protect Earth from potential asteroid impacts, including the recent OSIRIS-REx mission. Additionally, smaller asteroids 2024 EQ and 2024 EK4 are also expected to pass by Earth this weekend.
