NASA Updates Risk Assessment for Potential “City Killer” Asteroid
The National Aeronautics and Space Administration (NASA) has released the latest information about an asteroid dubbed a “city killer,” which could potentially impact Earth within the next eight years. The space agency predicts that the asteroid, designated 2024 YR4, has a 1 to 32, or 3.1 percent, chance of hitting Earth on December 22, 2032.
In a recent update, NASA has reduced this risk, predicting that there is only a 1 to 67 (1.5 percent) chance that the asteroid will impact Earth. This revised assessment was announced on social media sites, with NASA explaining that the predictions are based on better asteroid observations.
The asteroid is estimated to be 90 meters (300 feet) in size, comparable to the size of Big Ben, the iconic clock tower in London. This size is significant because it falls within the category of asteroids that could cause catastrophic damage if they were to hit a populated area.
David Rankin, a scientist from the Catalina Sky Survey project at NASA, has projected the “risk corridor” for the asteroid, which shows the large part of the Earth that could be impacted. The risk corridor stretches from South America, across the Pacific Ocean, through South Asia, the Arabian Sea, and Africa.
“Certain countries that may face impacts include Venezuela, Colombia, Ecuador, India, Pakistan, Bangladesh, Ethiopia, Sudan, and Nigeria,” Rankin said. The exact location of the impact depends on the Earth’s rotation at the time of a potential collision.
To determine the potential damage, an international team used the James Webb Space Telescope. The asteroid Tunguska, which hit Siberia in 1908, was similar in size and destroyed 830 square miles of forest. This historical event serves as a grim reminder of the potential devastation that could occur if a similar-sized asteroid were to hit a densely populated area.
The asteroid 2024 YR4 was first discovered in December 2024 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile, which is funded by NASA. At that time, the possibility of impact was only 1.3 percent, but it still ranked at the top of NASA’s risk list.
It is estimated that the asteroid could flatten buildings for as far as two miles in any direction from the point of impact. This underscores the importance of continued monitoring and preparedness efforts.
The potential impact of such an asteroid highlights the need for robust planetary defense systems. NASA and other space agencies around the world are actively working on technologies to deflect or destroy asteroids that pose a threat to Earth. For instance, the Double Asteroid Redirection Test (DART) mission, launched in 2021, successfully demonstrated the ability to alter the trajectory of an asteroid by crashing a spacecraft into it.
While the risk of a direct impact is relatively low, the potential consequences are severe. This is why NASA and other organizations continue to invest in early detection and mitigation strategies. The use of advanced telescopes and space-based observatories, such as the James Webb Space Telescope, plays a crucial role in identifying and tracking potentially hazardous asteroids.
NASA’s efforts are part of a broader international collaboration to ensure the safety of Earth from asteroid impacts. The Space Missions Planning Advisory Group (SMPAG), an international group of space agencies, works together to develop strategies for planetary defense.
In the event of a potential impact, emergency response plans would be activated, involving coordination between government agencies, first responders, and international organizations. The U.S. Federal Emergency Management Agency (FEMA) and other relevant agencies would play a key role in preparing for and responding to such an event.

# NASA Updates Risk Assessment for Potential “City Killer” Asteroid
## Overview
Recent updates from NASA have recalibrated the risk posed by asteroid 2024 YR4, a near-Earth object with a low but noteworthy chance of impacting Earth in the future. This article provides detailed answers to prevalent questions about the asteroid and NASA’s planetary defense strategies.
## Frequently Asked Questions
### What is Asteroid 2024 YR4 and its potential risk to Earth?
asteroid 2024 YR4 is a near-Earth object estimated to be 90 meters in size and was first identified in December 2024. NASA has assessed that there is a 1 to 67 (1.5 percent) chance it could impact Earth on December 22, 2032. Originally, the risk estimation stood at a 1 to 32 (3.1 percent) probability before being updated based on improved observational data [[1]][[2]].
### Why is the size of Asteroid 2024 YR4 meaningful?
The asteroid is about 90 meters (300 feet) long, roughly the size of London’s Big Ben. Asteroids of this magnitude fall within the “city killer” category, capable of causing catastrophic damage upon impact due to their significant energy release when colliding with Earth. The past Tunguska event in Siberia – caused by a similar-sized asteroid – destroyed 830 square miles of forest, illustrating the potential devastation [[1]].
### How has NASA updated its risk assessment for this asteroid?
through enhanced observational techniques, NASA has reduced the impact probability from 3.1% to 1.5%. These updates are part of NASA’s ongoing effort to improve predictions by using data from telescopes like the James Webb Space Telescope and other observation tools [[3]].
### What is a “risk corridor” in the context of asteroid impacts?
A “risk corridor” identifies the areas on Earth that could be affected by an asteroid impact. For 2024 YR4, David Rankin from the Catalina Sky Survey at NASA outlines a path stretching from South America, through the Pacific ocean, and across South Asia to africa. this corridor considers where the asteroid could land based on the Earth’s rotation [[1]].
### Which countries are at potential risk from an impact of 2024 YR4?
Countries that could be affected,depending on the impact point,include Venezuela,Colombia,Ecuador,India,Pakistan,Bangladesh,Ethiopia,Sudan,and Nigeria. The exact point of impact varies depending on the Earth’s rotation and trajectory at the time of potential collision [[1]].
### What are NASA’s planetary defense strategies?
NASA and international space agencies are developing technologies to preemptively address asteroid threats. The Double Asteroid Redirection Test (DART) mission demonstrated altering an asteroid’s trajectory by crashing a spacecraft into it. Continuous innovations aim to enhance Earth’s defenses against such potential calamities [[1]].
### what role do telescopes play in identifying potentially hazardous asteroids?
Advanced telescopes and space-based observatories, like the James Webb Space Telescope, play a crucial role in detecting and monitoring near-Earth objects. Their capabilities support early identification and trajectory predictions,allowing for timely risk assessments and defensive measures [[1]].
### How do international organizations work together for planetary defense?
The Space missions Planning Advisory Group (SMPAG), consisting of various space agencies, collaborates on strategies for planetary defense. Joint efforts ensure coordinated responses in the event of an impending asteroid threat [[1]].
### What emergency response measures are in place for potential asteroid impacts?
In the event of a potential impact, coordinated response plans involving government agencies, first responders, and international organizations, including the U.S. Federal Emergency Management Agency (FEMA),would be activated. These measures aim to prepare for and mitigate potential consequences of an asteroid collision [[1]].
### conclusion
While the probability of an impact from asteroid 2024 YR4 is relatively low, the importance of continued monitoring and preparedness cannot be understated. NASA and international partners remain committed to developing robust planetary defense systems to safeguard Earth from potential future asteroid threats.
