Guam- This week, Earth will witness the close approach of five asteroids, with the largest ones being as large as a plane. Although these large space objects are not a threat to Earth, their presence highlights the importance of closely monitoring near-Earth objects (NEOs) and understanding their trajectories.
According to NASA, the first asteroid, named 2023 RG, is expected to fly past Earth on Friday, at a distance of approximately 1 million miles. This will be followed by three other asteroids, namely 2023 RH, 2023 QC5, and 2020 GE, which will approach our planet within a range of 1 million to 3.6 million miles on the same day. Finally, on September 9, the asteroid named 2023 RL will pass by Earth at a relatively closer distance of 469,000 miles.
While these asteroids may seem relatively close, NASA considers any space object within 120 million miles of Earth as a “near-Earth object”. Additionally, any object within 4.65 million miles is categorized as “potentially hazardous”. Therefore, while the asteroids passing by this week pose no immediate danger, it’s essential to stay vigilant and continuously monitor the ever-changing paths of these celestial bodies.
To track the locations and orbits of these potentially hazardous asteroids, NASA currently monitors approximately 28,000 space rocks. This proactive approach allows scientists to predict potential threats accurately, considering factors such as the Yarkovsky effect, which can subtly alter the objects’ orbits over time.
Although smaller asteroids may not pose an immediate danger, past events have shown the potential for significant damages and injuries. For instance, in 2013, the explosion of a meteor over Chelyabinsk, Russia, caused extensive destruction and injuries. Therefore, understanding the trajectories of these space objects is crucial to mitigating potential threats and preparing appropriate deflection strategies.
Space agencies worldwide are actively developing technologies to deflect dangerous asteroids and protect Earth. One such initiative is the Double Asteroid Redirection Test (DART) spacecraft, which seeks to alter the trajectory of an asteroid by crashing into it. Additionally, China is planning an asteroid-redirect mission to divert an asteroid called Bennu from a potentially catastrophic impact with Earth. These efforts underline the urgency to bolster collaborative global efforts in monitoring and safeguarding against NEOs.
As the week progresses and these five asteroids pass by Earth, it is a reminder of the vast universe we inhabit and the potential threats it poses. Through ongoing monitoring, advanced research, and international collaboration, we can better understand the cosmos around us and protect our planet from any future impacts.
