The discovery and tracking of 2024 LB4 are part of NASA’s ongoing efforts to monitor Near-Earth Objects (NEOs) that could potentially pose a threat to our world. While the term “plane size” may conjure up images of catastrophic impact, it is important to understand the context and scale of the space. The distance at which LB4 will pass in 2024 is considered safe by astronomical standards, as it is almost eight times the distance between the Earth and the Moon.

NASA’s Jet Propulsion Laboratory (JPL) keeps a close eye on such celestial bodies through its Center for Near-Earth Object Studies (CNEOS). Using a network of telescopes and radar systems, CNEOS calculates the orbits, sizes and potential hazards of asteroids such as 2024 LB4. This particular asteroid is one of many that routinely sweep past Earth, a reminder of our solar system’s dynamic and ever-changing environment.
For the unfamiliar, NASA’s Jet Propulsion Laboratory (JPL) is a renowned research and development center specializing in the construction and operation of planetary spacecraft. JPL focuses on the exploration of the solar system and beyond, with an emphasis on robotic missions to study planets, moons, comets and asteroids. The laboratory also develops technology and missions to monitor changes in the Earth’s atmosphere, climate and surface.
Tracking asteroids is a complex process that involves observing the object over time to refine its orbit and predict future paths. For LB4 in 2024, observations have provided enough data to assure scientists that its journey will not end in a collision with Earth. However, the study of such objects provides valuable insights into the composition and behavior of asteroids, which could inform future missions or planetary defense strategies.
NASA’s Planetary Defense Coordination Office (PDCO) is charged with identifying and mitigating potential threats from NEOs. In collaboration with other U.S. agencies and international partners, the PDCO develops and coordinates efforts to protect the Earth from impacts. One such effort was the Double Asteroid Redirection Test (DART) mission, which successfully changed the orbit of a small moon in the binary asteroid system Didymos, demonstrating a viable method for asteroid deflection.
The upcoming visit of asteroid 2024 LB4 is not an isolated event. It is part of a larger group of asteroids that will make their closest approach to Earth in June 2024. These include asteroid 2024 LZ2, which will come within 800,000 miles of Earth on June 14, and asteroid 2024 LH3, a larger body measuring 150 feet. , which will maintain a safe distance of 3,090,000 miles on June 16.
Exploring and monitoring asteroids is essential for increasing our knowledge of the cosmos and protecting Earth. While LB4 of 2024 is not a threat, it is a testament to the ability of NASA and its partners to keep a close eye on the universe. The wisdom we gain from these close interactions broadens our understanding and allows us to address any problems that may come from our heavenly neighbors in the future.
