A Close Call with a Cosmic Rock

A huge rock from space, named 2024 YR4, was first spotted in 2024. Scientists had a close look at it for two months. They found out that it won't hit Earth in 2032. The chances of it hitting Earth were very low, just 0. 0017%. This means it will fly by our planet without causing any harm. The European Space Agency even put the odds lower, at 0. 001%. This is a big relief. Just a week before, the rock had a 1. 5% chance of hitting Earth. At one point, the risk was as high as 3. 1%, making it the most dangerous asteroid in a decade. Scientists expected the odds to go up and down, which is exactly what happened. If this rock had hit Earth, it would have been a disaster. It could have released energy equal to 8 megatons of TNT, which is 500 times more powerful than the atomic bomb dropped on Hiroshima. This could have threatened the lives of hundreds of millions of people. But luckily, that won't happen.The moon, however, might still be in danger. There's a 1. 7% chance that the asteroid could hit our natural satellite. The moon doesn't have an atmosphere to protect it, so the impact would be huge. It would leave a crater between 1, 640 to 6, 500 feet across. Scientists will use the James Webb Space Telescope to get a better look at the asteroid. This telescope is the most powerful in the world. They hope to find out more about its size before it disappears from view in a month or two. This close call has been a great learning experience for astronomers. Even though the asteroid no longer poses a threat to Earth, it has given scientists a chance to study it closely. This will help them understand more about these cosmic rocks and how to protect our planet from future threats.
