The asteroid 2024 YR4 has a very small chance of striking Earth when its orbit briefly intersects our planet's in December 2032. Feb 21 Asteroid's odds of hitting Earth fluctuate as NASA tasked with studying it
But NASA says it is being targeted as a more effective way to test the crash method instead of striking a single asteroid flying through space. 美国宇航局表示,这是一种更有效的测试碰撞方法的方法,而不是撞击在太空中飞行...
