As part of its ongoing efforts to monitor near-Earth objects (NEOs), NASA’s Jet Propulsion Laboratory (JPL) is currently tracking three sizable asteroids on a trajectory that will bring them close to our planet on March 16, 2026. While the term ‘close approach’ may sound alarming, the agency assures that these celestial bodies pose no threat to Earth and will safely pass at considerable distances.
Details of the Asteroids
Among the asteroids being monitored are:
- 2026 ET2: Measuring approximately 25 feet wide, this asteroid is set to approach Earth at a distance of about 495,000 miles.
- 2026 EY2: Slightly larger at 34 feet wide, it will be on a path that brings it roughly 987,000 miles away from our planet.
- 2026 CR3: The largest of the trio, this asteroid measures an impressive 230 feet wide and will pass at a distance of approximately 4,640,000 miles.
Understanding Near-Earth Objects
Near-Earth objects, particularly asteroids, are defined as space rocks that come within 1.3 astronomical units (AU) of the Earth’s orbit. One AU is the average distance from the Earth to the Sun, approximately 93 million miles. NASA has been vigilant in tracking these objects to ensure that any potential threats to our planet are identified and studied in advance.
The majority of asteroids that come into proximity with Earth are relatively small, often measuring no more than a few dozen feet across. In the case of the asteroids tracked by NASA, they range from the size of a bus to that of a small airplane. While the sizes may seem modest compared to other celestial bodies, their close approaches still provide valuable opportunities for research.
Scientific Opportunities from Close Approaches
Each close approach of an asteroid offers scientists a unique chance to study these ancient remnants from the solar system’s formation. By closely monitoring their paths, speeds, and compositions, researchers can gain insights into the history of our solar system, as well as improve our understanding of potential hazards.
NASA’s NEO program employs advanced telescopes and radar to track these objects, collecting data that can help predict future trajectories. This capability is crucial for assessing whether any NEO could pose a risk to Earth in the future. The agency’s ability to detect and characterize asteroids has improved significantly over the years, leading to a more comprehensive catalog of NEOs.
Public Awareness and Education
NASA’s transparency in communicating about these asteroids serves not only to inform the public but also to alleviate fears associated with potential asteroid impacts. The agency regularly updates its databases and public resources so that individuals can stay informed about the state of NEOs that come close to Earth.
The passage of these asteroids in 2026 will not only be a safe event but also a reminder of the dynamic environment of our solar system. As awareness of NEOs grows, so does public interest in the science behind planetary defense and asteroid tracking.
The Future of Asteroid Monitoring
As technology continues to advance, so too will our capabilities in tracking and analyzing near-Earth objects. Upcoming missions, such as NASA’s DART (Double Asteroid Redirection Test), aim to test our ability to change the trajectory of an asteroid. This pioneering mission, which involves intentionally crashing a spacecraft into an asteroid, will provide critical data on how to deflect potentially hazardous asteroids in the future.
In addition to DART, various international collaborations are underway to enhance the global monitoring of asteroids. The sharing of data and resources across nations will be essential in developing a robust planetary defense strategy.
Conclusion
NASA’s ongoing efforts to track and study asteroids are crucial for understanding potential risks they may pose to Earth. The three asteroids slated for close approaches in March 2026 are not a cause for concern; rather, they are an opportunity to learn more about the universe around us. As scientists continue to monitor these celestial bodies, we can appreciate the beauty and complexity of our solar system while ensuring the safety of our planet.
