NASA warns that a 98ft plane-sized asteroid is heading towards Earth soon
etimes.in | Jun 20, 2024, 03.52 PM IST
NASA’s vigilant eyes in the sky have detected an asteroid, designated as 2024 LB4, that is projected to make a close approach to Earth. This asteroid, comparable in size to a commercial airliner at approximately 98 feet in diameter, is on a trajectory that will bring it within 1,800,000 miles of our planet. The anticipated date of this encounter is June 16, 2024, a day when the asteroid will zip past Earth at a staggering speed of 7.59 kilometers per second.
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-sized’ might evoke images of a catastrophic impact, it’s important to understand the context and scale of space. The distance at which 2024 LB4 will pass is considered safe by astronomical standards, as it is nearly eight times the distance between Earth and the Moon.
NASA’s Jet Propulsion Laboratory (JPL) maintains a watchful eye on such celestial bodies through its Center for Near-Earth Object Studies (CNEOS). Utilizing a network of telescopes and radar systems, CNEOS calculates the orbits, sizes, and potential hazards of asteroids like 2024 LB4. This particular asteroid is one of many that routinely sweep by Earth, a reminder of the dynamic and ever-changing environment of our solar system.
For the unversed, NASA’s Jet Propulsion Laboratory (JPL) is a renowned research and development center specializing in the construction and operation of robotic planetary spacecraft. JPL is dedicated to the exploration of the solar system and beyond, focusing on robotic missions to study planets, moons, comets, and asteroids. Also, the laboratory also develops technology and missions to monitor Earth's atmosphere, climate, and surface changes.
The tracking of asteroids is a complex process that involves observing the object over time to refine its orbit and predict future paths. For 2024 LB4, 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 offers valuable insights into the composition and behavior of asteroids, which can inform future missions or planetary defense strategies.
NASA’s Planetary Defense Coordination Office (PDCO) is tasked with the identification and mitigation of potential threats from NEOs. In collaboration with other U.S. agencies and international partners, the PDCO develops and coordinates efforts to protect Earth from impacts. One such effort was the Double Asteroid Redirection Test (DART) mission, which successfully altered the orbit of a small moonlet in the binary asteroid system of Didymos, demonstrating a viable method of asteroid deflection.
Asteroid 2024 LB4’s upcoming visit 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 823,000 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.
The vigilant observation of asteroids, such as 2024 LB4, underscores the critical role of space agencies like NASA in cosmic surveillance and planetary defense. These efforts not only enhance our cosmic knowledge but also fortify Earth’s defenses against potential asteroid impacts. The data collected from tracking objects like 2024 LB4 enriches our scientific repository, informing strategies to mitigate celestial threats. This proactive approach in understanding the intricate dynamics of near-Earth objects (NEOs) ensures that humanity is better prepared to address any future challenges posed by the vast and unpredictable expanse of space.
About Center for Near-Earth Object Studies (CNEOS)
The Center for Near-Earth Object Studies (CNEOS), operated by NASA’s Jet Propulsion Laboratory (JPL), is a pivotal establishment dedicated to the calculation of orbits for asteroids and comets, assessing their probability of Earth impact. Located at Caltech in Pasadena, California, CNEOS is responsible for the high-precision orbit solutions that determine close approaches to Earth and evaluate impact probabilities for the next century or more. It houses the Sentry impact monitoring system and the Scout system, which analyze potential future orbits of hazardous asteroids and compute possible future motions, respectively. In the event of a potential impact, CNEOS estimates the impact time and probability, playing a crucial role in planetary defense.
In addition to Sentry, CNEOS operates the Scout system, which vigilantly monitors new potential asteroid discoveries and computes the possible range of future motions, even before these objects have been confirmed as discoveries. This proactive approach is essential in the event of a predicted impact, where CNEOS’s expertise is called upon to predict the impact time, location, and geometry. Through collaboration with the Aerospace Corp., CNEOS also provides the NEO Deflection App, which calculates how far a hypothetical asteroid would move if deflected by a known amount at an earlier time. This capability is crucial for developing hypothetical impact scenarios used at Planetary Defense Conferences and similar exercises, underscoring CNEOS’s pivotal role in planetary defense.
