小行星或在2032年撞击地球？
Scientists found an asteroid (小行星) called 2024 YR4. It is big. It might come near Earth in 2032. But the chance of it hitting Earth is small, only 0.28%. ▲ — it will likely miss our planet!
Scientists watch the asteroid carefully. They learn more about it. If needed, they can try to push it away. Scientists will keep watching it until May, 2025. After that, they can not see it again until 2028.
