NASA’s Jet Propulsion Laboratory (JPL) is closely monitoring three asteroids that will pass Earth on December 11, 2024. Although their proximity may raise concerns, scientists assure that none of these celestial bodies pose any threat. Instead, their approach provides researchers with an invaluable opportunity to study near-Earth objects (NEOs) and deepen our understanding of the Solar System.
Details of 3 Asteroids Passing Earth on December 11, 2024
Asteroid 2018 XU3: Largest Near-Earth Object Passes Safely on December 11, 2024
Asteroid 2018 XU3 is the largest of the three, measuring about 89 feet across — about the size of a commercial airliner’s wingspan. It will pass through a safe distance of 4 million miles, which is 16 times the distance between the Earth and the Moon.
The asteroid’s size and relatively close approach make it an ideal candidate for observation. By examining its composition, scientists aim to gather insights into the structure and behavior of large NEOs, which can help improve models of asteroid formation and motion.

Asteroid 2024 XZ11: Near-Earth Object Offering Unique Research Opportunities
Slightly smaller than 2018 XU3, Asteroid 2024 XZ11 is 71 feet wide and will pass Earth at a distance of 2.92 million miles. Although it is small, its proximity allows for high-resolution imaging and spectral analysis.
This asteroid presents a valuable opportunity for researchers to compare its physical and chemical properties with those of larger asteroids. These comparisons help increase our knowledge of the diversity among space objects, improving our ability to characterize them.
Asteroid 2024 XL11: Smallest Near-Earth Object Passes by Earth in December 2024
The smallest of the three, Asteroid 2024 XL11, is only 20 feet wide, about the size of a small car. Despite its size, it will be the closest it will ever come to Earth, passing by at a distance of 735,000 miles – nearly three times the distance to the Moon.
Its proximity gives scientists a unique opportunity to observe how small asteroids interact with Earth’s gravitational forces. Smaller asteroids like 2024 XL11 are often ejected from larger bodies, and studying their behavior can reveal important details about their structural integrity and how they might behave if they enter Earth’s atmosphere.
Why does NASA monitor these asteroids?
The careful tracking of these asteroids underscores NASA’s commitment to planetary protection and scientific discovery. By closely monitoring their trajectories, scientists can validate prediction models and ensure that early warning systems for hazardous objects remain accurate. Additionally, these meetings provide opportunities to test and improve technologies for observing and analyzing space objects.
Asteroids are remnants of the early solar system, which hold important clues about its formation and evolution. Studying their structure, composition, and motion not only enhances our understanding of these ancient celestial bodies, but also informs strategies for planetary defense.
Studying near-Earth objects to enhance planetary defense and space exploration
Although none of the three asteroids pose a threat to Earth, their study will likely contribute to the development of tools and methods to reduce future threats from hazardous objects. These encounters remind us of the vastness of space and the importance of vigilance. Each asteroid flyby offers a glimpse into the complexities of our solar system and strengthens humanity’s ability to explore and protect our place within it. As these celestial objects make their way past Earth, they serve as a testament to the important role space exploration plays in securing our future.
