NASA Confirms Two Massive Asteroids Passing Close to Earth Today, No Threat Expected

Science News: NASA says two big asteroids, called 2025 OA3 and 2025 PA, are travelling through space and passing close to Earth. These space rocks are about 120 feet wide almost the size of a passenger aeroplane. Both are moving very fast, but scientists have said there is no danger, as they will pass Earth from a safe distance today.

Speeds and Distances of the Asteroids

The first asteroid, 2025 OA3, is travelling at a very high speed of 30,498 miles per hour. It will pass Earth at a distance of about 1.42 million miles. While these may seem like small distances in space terms, experts say there’s no risk of a collision with Earth.

Even though these are called near-Earth objects, they are still far enough to not cause any concern. NASA regularly tracks such objects to keep a close watch on any possible threats.

Why Studying Asteroids Is Important

Asteroids are not just space rocks; they are very old objects formed around 4.6 billion years ago—at the same time our solar system was created. By studying these ancient rocks, scientists can understand how the solar system formed and what conditions existed back then. This helps us learn more about Earth’s history and even how life may have started here.

In the past, some asteroids have hit Earth with serious effects. One such impact is believed to have led to the extinction of the dinosaurs. This is why space agencies always keep an eye on these rocky bodies.

How NASA Keeps Earth Safe

NASA’s Jet Propulsion Laboratory (JPL) uses special radar tools to follow the paths of asteroids. This technology helps scientists predict when and how close these objects will come to Earth. NASA has also sent missions like OSIRIS-REx and Japan's Hayabusa2 to collect samples from asteroids. These samples help scientists understand more about the building blocks of life.

They will pass by without causing harm. But every time an asteroid comes close, it gives scientists another chance to study space better and improve ways to protect Earth in the future.
