What are asteroids and how do they affect Earth in a way that kids can understand?

Answer 1

Asteroids are rocky objects that orbit the Sun, and sometimes they can come close to Earth. When an asteroid collides with Earth, it can cause a big explosion, like a giant firework. This explosion can create a lot of heat and dust, which can block out sunlight and affect the Earth's climate. Scientists study asteroids to understand their movements and protect Earth from potential impacts.
