According to the Washington Post, Earth remains dangerously unprepared for the threat posed by “city-killer” asteroids, despite the potential for catastrophic impacts on populated areas.
NASA has catalogued more than 40,000 asteroids that approach Earth’s orbit, with the vast majority of discoveries occurring in recent decades. While scientists have identified over 95 percent of the roughly 1,000 civilization-ending asteroids larger than two-thirds of a mile in diameter, a more immediate danger comes from smaller but still devastating objects.
Experts estimate there are about 25,000 “city killers” — asteroids roughly seven times the size of the 2013 Chelyabinsk meteor — yet only 45 percent have been found. This leaves more than 14,000 such near-Earth objects unaccounted for, any of which could strike without warning.
A vivid reminder of the peril came on February 15, 2013, when a 66-foot meteor exploded over Chelyabinsk, Russia. The event released energy equivalent to about 30 times that of the Hiroshima bomb, injuring roughly 1,600 people. “That meteor broke up in the atmosphere, sparing the city from worse. But Earth might not be so lucky next time,” the report notes.
Simulations show that a 460- to 520-foot asteroid detonating in an airburst could unleash 60 to 105 megatons of energy — far exceeding the Hiroshima blast — devastating everything within a nine-mile radius and causing serious damage up to 60-75 miles away. Such impacts, though rare, occur roughly once every 11,000 years, representing a significantly higher annual risk than dying in a plane crash.
Planetary defense experts advocate for a robust strategy centered on enhanced detection and deflection. Ground-based efforts like the Vera C. Rubin Observatory in Chile promise to dramatically increase known asteroids, while NASA’s Near-Earth Object Surveyor, an infrared space telescope slated for launch in late 2027, aims to address blind spots near the sun.
Deflection technology, proven by NASA’s 2022 DART mission, requires pre-positioned spacecraft ready for rapid deployment rather than building from scratch in a crisis.
The article suggests that a fleet of 10 such impactors could be developed for around $3.25 billion — comparable to the cost of a new NFL stadium — and calls for international cooperation, including potential exceptions to space nuclear test bans for genuine threats.
