NASA's radar detected an asteroid that could impact Earth in 10 years, prompting global readiness, though failure of deflection missions still poses significant risks.
A report indicated that Earth would need at least 14 years' notice to prepare for an asteroid impact, highlighting the essential nature of early detection.
NASA and other agencies are developing early-warning systems to identify potential threats, but current technology only allows for detection of larger asteroids long before they reach Earth.
Recent events underline the urgency of preparedness; even small asteroids, like the one detected above the Philippines, can go unnoticed until minutes before impact.
