BREAKING: NASA Discovers a Dangerous Big Asteroid That May Hit Earth! (Video)
By: SpaceEyeNews
Discovery and Initial Observations
NASA has detected a new asteroid, 2024 YR4, that has a small but significant chance of colliding with Earth in 2032. The Asteroid Terrestrial-impact Last Alert System (ATLAS) first spotted the space rock in December 2024, and its trajectory has since been closely analyzed.
According to the Center for Near Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory, this asteroid belongs to the Apollo group, a classification for asteroids that cross Earth’s orbit. Its estimated size is between 40 and 90 meters (130 to 300 feet), making it potentially destructive if it impacts a populated area.
What makes this discovery particularly interesting is how early scientists detected it. Typically, near-Earth objects (NEOs) are identified only a few months or years before a potential impact. Spotting 2024 YR4 nearly a decade in advance showcases the growing capabilities of space surveillance systems like ATLAS and NASA’s NEO Surveyor program, which aims to track hazardous asteroids before they become imminent threats.
The asteroid’s current orbital path suggests a potential close approach to Earth on December 22, 2032. While the likelihood of a collision is still being calculated, NASA scientists are taking it seriously, making 2024 YR4 one of the most closely watched objects in space today.

Impact Probability and Risk Assessment
Initial models placed the probability of 2024 YR4 impacting Earth at 1.4%, but further observations have slightly increased this estimate to 2.3%—equivalent to about a 1 in 43 chance of impact. While that might sound small, it is currently the highest impact probability of any known large asteroid.
To assess the risk, NASA uses the Torino Impact Hazard Scale, a system that categorizes the likelihood and potential damage of an asteroid collision. 2024 YR4 is currently rated a ‘3’ on this scale, meaning it merits attention but does not yet pose a significant threat. To put this into perspective, most near-Earth objects are rated at Torino 0, meaning no risk. The fact that this asteroid has reached level 3 means scientists are taking it seriously.
However, astronomers stress that asteroid impact predictions evolve over time. The more data they collect, the more refined the projections become. In many cases, as new observations come in, the probability of impact decreases dramatically. This is why continued monitoring and tracking of 2024 YR4 will be crucial in the coming years.
Potential Consequences of an Impact
The size of 2024 YR4 means that if it were to collide with Earth, it could cause regional devastation, particularly if it impacts a heavily populated city.
For comparison, the 1908 Tunguska event in Siberia—caused by a similarly sized asteroid—released the energy equivalent of 10-15 megatons of TNT, flattening 2,000 square kilometers (770 square miles) of forest. Had it struck a city, the destruction would have been catastrophic.
Another comparable event is the Chelyabinsk meteor that exploded over Russia in 2013. At just 17 meters (56 feet) wide, that asteroid shattered windows across six cities and injured over 1,500 people. The impact of 2024 YR4, which could be up to five times larger, would be significantly more powerful.
If the asteroid were to land in the ocean, the consequences could vary. A deep-water impact might create a massive tsunami, depending on its angle and velocity. However, the vast majority of Earth’s surface is uninhabited, so there’s also a high probability that, even if it impacts, it may not directly threaten human populations.
Ongoing Monitoring and Future Observations
Scientists around the world are keeping an eye on 2024 YR4, using telescopes such as:
- NASA’s Goldstone Radar in California, which helps refine asteroid orbits.
- The European Space Agency’s (ESA) Flyeye Telescope, a tool designed to track NEOs.
- The Pan-STARRS observatory in Hawaii, which specializes in identifying space rocks before they reach Earth.
Future observations will provide more precise orbital calculations. These calculations will determine whether 2024 YR4 is on a collision course or will safely pass by Earth.
NASA has already planned additional radar tracking sessions over the next few years. By 2027, astronomers expect to have an accurate assessment of the asteroid’s final trajectory. Until then, every new observation could increase or decrease the estimated risk.
Planetary Defense Strategies
NASA and other space agencies are actively working on planetary defense technologies to counter potential asteroid threats. Some key methods being explored include:
- Kinetic Impactor (DART Mission): In 2022, NASA successfully tested its Double Asteroid Redirection Test (DART), impacting an asteroid to change its trajectory. If necessary, a similar strategy could be used against 2024 YR4 to push it off course.
- Nuclear Deflection: While this remains a last-resort option, some experts believe a nuclear explosion in space could be used to alter an asteroid’s path.
- Gravity Tractors: This concept involves sending a spacecraft to fly alongside an asteroid, using its gravitational pull to gradually shift the rock’s trajectory over time.
Currently, NASA’s NEO Surveyor Mission, planned for launch in 2027, is expected to further refine our ability to detect and track asteroids like 2024 YR4 well in advance.
Public Communication and Preparedness
While asteroid 2024 YR4 is a serious object of interest, it is important to avoid unnecessary panic. Space agencies emphasize that even in the worst-case scenario, there will be years of preparation time. Governments and scientists can use this time to develop evacuation plans, impact mitigation strategies, and potential asteroid-deflection missions.
If the impact probability increases significantly, NASA and the International Asteroid Warning Network (IAWN) will issue formal impact warnings, ensuring early evacuations if necessary.
It’s crucial that accurate information is shared with the public to prevent misinformation and unnecessary fear. As seen with past asteroid encounters, early detection and transparency are key to handling potential threats responsibly.
Final Thoughts: What This Means for the Future
NASA’s discovery of 2024 YR4 serves as both a warning and a success story. It highlights the importance of early detection, showcasing how modern technology allows scientists to predict asteroid threats years in advance. This gives humanity time to prepare and, if necessary, respond.
While the 2.3% impact probability remains low, continued monitoring will refine our understanding of this asteroid’s path. The most likely scenario is that further observations will rule out an impact entirely, as has happened with other past asteroid threats.
However, this event is a crucial reminder of the need for planetary defense programs. The success of DART, the launch of NEO Surveyor, and global asteroid monitoring efforts show that Earth is better prepared than ever before.
For now, all we can do is stay informed and trust the scientists working tirelessly to keep us safe. The next few years will provide more answers, and SpaceEyeNews will continue to bring you the latest updates on this fascinating discovery.
Stay tuned for more on asteroid 2024 YR4 and what it means for the future of planetary defense.
