NASA considers nuking asteroid 2024 YR4 to save the Moon from impact

September 30, 2025 9:45 am

Researchers say we can use two 100-kiloton nuclear bombs to destroy the asteroid 2024 YR4 from hitting the Moon.

Its goal is to orbit and land on the tiny asteroid to learn more about its composition and structure. The mission previously rendezvoused with the 900-metre (2,953-foot) wide asteroid Ryugu in 2020 and returned samples to Earth. (Image for representation: Freepik)
