Asteroid 2024 YR4: What We Know About Its Potential Impact in 2032
Recently, the asteroid 2024 YR4 has been making headlines due to its potential to collide with Earth in 2032. Although the likelihood of an impact is quite low—only about 2%—this space rock is still under close scrutiny by astronomers around the world. With the aid of advanced telescopes, scientists are working to gather as much information as possible to ensure we're ready for any possible threat it may pose.
Discovered by NASA's Asteroid Terrestrial-impact Last Alert System (ATLAS) in December 2024, 2024 YR4 has sparked the interest of both space agencies and astronomers alike. The asteroid is estimated to be between 131 and 295 feet (40 to 90 meters) wide—roughly the size of a large building. While this size is far smaller than the asteroid that wiped out the dinosaurs 66 million years ago, it could still cause significant regional damage if it were to strike Earth.

Currently, the asteroid is over 30 million miles away from our planet and moving farther out as it orbits the Sun. As it continues its path, astronomers are relying on both Earth-based and space-based observatories to gather more precise data. The James Webb Space Telescope, set to start observations in March, will play a key role in providing a clearer picture of the asteroid's size and trajectory by detecting its heat emissions, which will allow scientists to refine their calculations.
Although smaller asteroids do hit Earth regularly, often disintegrating in the atmosphere, 2024 YR4 is a significant focus for researchers because of its potential to cause destruction on a larger scale. A potential impact from this asteroid could lead to blast damage up to 31 miles (50 kilometers) from the impact site, especially if it enters the atmosphere at its predicted speed of about 38,000 miles per hour (17 kilometers per second).
If this asteroid does pose a genuine threat, it could create a scenario similar to the Tunguska event in 1908, which devastated a large area in Siberia. However, the good news is that the risk of impact in 2032 remains extremely low, and scientists are continually monitoring its movements. They will also continue to track the asteroid when it is next visible in 2028.
In the meantime, the global effort to track and understand near-Earth objects like 2024 YR4 is crucial. Technologies such as the James Webb Space Telescope provide us with vital tools to assess these risks, so we can prepare for any potential threats from space. For now, the scientific community is committed to staying ahead of these cosmic dangers, ensuring that the risks to Earth are thoroughly evaluated and understood.
