NASA is closely monitoring a newly-discovered near-Earth asteroid that poses a slight chance of colliding with our planet in 2032. The massive asteroid, named 2024 YR4, was detected by a Chilean telescope and measures between 130ft and 330ft (40m to 100m) in size, comparable to the London Eye. The probability of impact is just over 1 per cent, prompting experts to keep a vigilant eye on its movements.
Paul Chodas, director of NASA’s Centre for Near Earth Object Studies, reassures that there is a 99 per cent chance the asteroid will miss Earth. However, he emphasises the importance of monitoring it closely as it moves away from our planet and its solar orbit becomes clearer. Top telescopes worldwide will continue tracking the asteroid to refine estimates of its size and trajectory, as it will not be observable again until its return in 2028.
The asteroid made its closest approach to Earth on Christmas Day, coming within about 500,000 miles (800,000km), or twice the lunar distance. Scientists are also looking back at sky surveys from 2016 to gather more data on its trajectory. While the impact location is yet to be determined if it were to strike, authorities confirm that no significant asteroids currently show a likelihood of impact higher than 1 per cent.
The European Space Agency underscores the importance of remaining vigilant, as Earth is subject to such cosmic encounters every few millennia. With NASA highlighting December 22, 2032, as a possible date of impact, ongoing observations will provide crucial information for future predictions. While the risk level for this specific asteroid is expected to decrease as more data is gathered, the thorough monitoring and analysis demonstrate the proactive approach taken by space agencies to ensure Earth’s safety from potential asteroid threats.
In conclusion, the diligent monitoring and analysis conducted by NASA and other space agencies highlight the importance of being prepared for potential cosmic threats. The collaborative efforts to track and study near-Earth asteroids ensure that any potential risks can be effectively assessed and mitigated, showcasing the scientific community’s commitment to planetary safety and protection.
