In a significant and unexpected development, NASA has redirected the James Webb Space Telescope (JWST) to study Asteroid 2024 YR4, after the probability of impact with Earth increased to 2.3%—double the previous estimate. This rare move highlights the growing concern among scientists and global leaders regarding the asteroid’s potential threat.
The Growing Concern
First discovered on December 27, 2024, Asteroid 2024 YR4 measures between 130 and 300 meters (427 to 984 feet) in diameter, making it comparable in size to the Eiffel Tower or three U.S. football fields end-to-end. While most near-Earth objects (NEOs) see their impact probabilities decrease with further observations, the latest data has increased concerns rather than alleviated them.
Initial impact risk assessments identified a broad “risk corridor” covering South America, the Pacific Ocean, South Asia, and the Middle East. However, refined tracking now places the highest likelihood of impact in South America, followed by the Pacific Ocean, South Asia, and the Middle East—between Nineveh (Mosul, Iraq) and Jerusalem.
NASA and Russia Explore Joint Deflection Strategy
In a potentially historic moment, a White House source has confirmed that President Donald Trump and Russian President Vladimir Putin discussed a joint asteroid deflection or destruction mission during recent high-level talks that initially focused on a prisoner exchange and Ukraine war negotiations. Given that the United States and Russia possess the world’s most powerful rockets and largest nuclear arsenals, they are currently the only two nations with the capability to attempt an asteroid deflection or destruction mission on short notice.
How Big of a Threat is 2024 YR4?
If Asteroid 2024 YR4 were to strike Earth, the effects would depend on its impact location:
South America Impact: A land impact in Venezuela, Colombia, or Ecuador could devastate major cities, ignite vast wildfires, and send dust into the atmosphere, cooling the planet for months or years.
Pacific Ocean Impact: A deep-sea strike could generate tsunamis hundreds of feet high, hitting coastal regions across the Pacific, including Hawaii, California, Japan, and the Philippines.
South Asia Impact: A strike in India, Pakistan, or Bangladesh would result in massive casualties in some of the world’s most densely populated areas, and could severely disrupt the global economy.
Middle East Impact: An impact between Nineveh and Jerusalem could cause catastrophic damage to Iraq, Syria, Israel, Jordan, and Lebanon, and could lead to unprecedented geopolitical instability.
With an estimated impact energy of 2,000–3,000 megatons of TNT, this asteroid could flatten entire cities, generate global tsunamis, and cause crop failures by blocking sunlight for an extended period.
How Would an Impact Affect Whittier, California?
While Whittier is not directly in the impact zone, the consequences of an asteroid strike in any of these locations would still be felt locally:
Tsunami Threat: If the asteroid strikes the Pacific Ocean, there is a potential for large tsunamis to reach the California coastline, causing flooding and infrastructure damage along coastal communities. While Whittier is inland, nearby cities like Long Beach and Los Angeles could see significant flooding, which could affect supply chains and transportation.
Economic Impact: A strike in South America, the Middle East, or South Asia could severely disrupt global trade, leading to higher gas prices, food shortages, and economic instability that would be felt in Whittier and throughout Southern California.
Climate Effects: If the impact sends enough debris into the atmosphere, it could cool global temperatures, potentially causing crop failures and extreme weather patterns, affecting local agriculture and food availability.
Power and Communications Disruptions: A major impact could interfere with global satellite systems, leading to internet outages and disruptions in communication, affecting residents and businesses in Whittier.
National Emergency Response: If the U.S. government begins implementing asteroid deflection measures, military and emergency response efforts could increase in California, potentially leading to changes in national policy that impact local communities.
Reasons for Cautious Optimism
Despite the alarming increase in impact probability, it is important to note that there is still reason for optimism:
The James Webb Space Telescope’s Data Could Lower the Impact Risk – NASA has emphasized that further analysis from JWST and the Hubble Space Telescope could allow scientists to refine their calculations and potentially reduce the probability of impact.
There is Nearly a Decade to Prepare – The asteroid is not expected to approach Earth until December 22, 2032, meaning that world governments and space agencies have eight years to develop and execute deflection strategies if necessary.
Planetary Defense Strategies Exist – NASA, Roscosmos, and other space agencies have been developing asteroid deflection strategies for years, including kinetic impactors (slamming a spacecraft into the asteroid) and nuclear deflection techniques.
What Happens Next?
NASA is expected to release additional findings as JWST and Hubble complete their observations of 2024 YR4. If new data reduces the probability of impact, public concern may ease. However, if further analysis increases the likelihood of a strike, world governments may accelerate planetary defense initiatives.
For now, scientists and policymakers urge calm but serious attention to the situation. With nearly a decade of preparation time, multiple deflection options on the table, and ongoing international cooperation, there is still a strong possibility that Earth can avoid disaster.
