Asteroids and Earth's Safety
Asteroids like 2024 YR4 are rocky remnants from the solar system's formation, often found in the Main Asteroid Belt between Mars and Jupiter. Near-Earth asteroids, whose orbits bring them close to Earth, are monitored due to their potential impact risk. The discovery of 2024 YR4 highlights the importance of global monitoring initiatives like NASA's DART Mission and ESA’s Hera Mission, which aim to mitigate potential threats. Understanding these dynamics is crucial for India's strategic goals in space exploration and disaster preparedness.
