Recent scientific analyses have brought new attention to asteroid 2023 DW, a massive near-Earth object now classified as a potential “city killer” with a predicted risk window around 2032. According to astronomers at the European Space Agency, this space rock’s current trajectory indicates multiple possible impact zones, with the South Pacific Ocean identified as having the highest probability. This revelation has intensified global monitoring efforts and revived international conversations about practical planetary defense strategies.
The asteroid threat and its discovery timeline
Asteroid 2023 DW was first observed in February 2023 by researchers at China’s Purple Mountain Observatory. Initially, it was categorized as a near-Earth object (NEO) with minimal threat, but subsequent observations have highlighted its unusual path and potential to cross Earth’s orbit. Measuring roughly 160 meters (around 525 feet) in diameter, 2023 DW is large enough to be considered a potentially hazardous asteroid, with the capacity to cause widespread regional destruction if it were to strike land.
When it was first tracked, scientists placed it at level 1 on the Torino Scale, indicating no unusual danger. However, as more orbital data was collected and calculations refined, the risk estimate has been updated to a Torino Scale rating of 2, meaning the object warrants ongoing attention but still poses a relatively low risk — estimated at about 1 in 670.

To improve the precision of these predictions, international monitoring is being coordinated through the International Asteroid Warning Network (IAWN). Multiple observatories worldwide contribute data, helping refine the asteroid’s orbital path and impact probability as it completes its 2.8-year orbit around the sun.
Scientists use a strict process to monitor threats like 2023 DW: beginning with initial discovery, they calculate its preliminary orbit, assess the impact risk, and continually refine its trajectory. This ongoing tracking includes analyzing physical properties such as size, composition, and rotation, all of which influence how effectively its path could be altered if needed.
Potential impact locations and consequences
Researchers have mapped out several possible impact zones for asteroid 2023 DW, with the South Pacific Ocean showing the highest likelihood. Estimates suggest this region has about a 68% chance of being within the impact corridor, centered roughly 1,500 kilometers east of New Zealand. Should this happen, a major ocean impact could generate powerful tsunami waves, with some models predicting they could reach heights of 10 to 15 meters near vulnerable coastlines.
Other lower-probability locations include sections of the Indian Ocean and remote parts of Central Asia. An ocean impact would mostly pose a tsunami threat, while a land impact could be devastating within a 50 to 100-kilometer radius. In a worst-case scenario, a direct land hit might create a crater several kilometers wide and an airblast strong enough to flatten buildings within a 30-kilometer zone.
NASA’s Center for Near Earth Object Studies (CNEOS) continues to update these impact projections as new observations become available. Meanwhile, global space agencies are exploring possible mitigation techniques. Building on the success of NASA’s DART mission in 2022, scientists are evaluating whether a kinetic impactor spacecraft could be launched years in advance to nudge the asteroid’s path just enough — even a velocity change of 2 centimeters per second could make the difference. Other methods like a gravity tractor are also under review but would require significantly more lead time.

The Planetary Defense Coordination Office is working closely with international partners including NASA, ESA, and JAXA to ensure that if asteroid 2023 DW’s threat level rises, the world will be ready with feasible deflection strategies. For now, while the impact risk remains relatively low, the discovery serves as a crucial reminder of why continued investment in tracking and planetary defense is essential for Earth’s future.
