NASA的JWST确认小行星2024 YR4不会撞击地球 可能前往月球 NASA's JWST confirms asteroid 2024 YR4 won't hit Earth, possibly heading for the Moon instead.

美国航天局的詹姆斯·韦伯空间望远镜更新了小行星2024年YR4的轨道,将其撞击地球的风险降低到零。 NASA's James Webb Space Telescope has updated the trajectory of asteroid 2024 YR4, reducing its risk of hitting Earth to zero. 该小行星先前估计在2032年12月22日撞击地球的概率为3.1%,但现在可能与月球相撞。 The asteroid, previously estimated to have a 3.1% chance of impacting Earth on December 22, 2032, may now potentially collide with the Moon instead. JWST于2025年5月进行的进一步观测将改进小行星的轨道和热特性。 Further observations by JWST in May 2025 will refine the asteroid's orbit and thermal properties. 如果撞击地球,撞击会释放相当于8兆吨TNT的能量,类似于大型核武器的破坏力。 If it had hit Earth, the impact would have released energy equivalent to 8 megatons of TNT, similar to the destructive power of a large nuclear weapon.
