Poynting–Robertson effect
The Poynting–Robertson Effect is a way that space dust and small particles like asteroids travel around in space. It's kind of like a moving sidewalk that helps you travel around in a shopping mall - it helps space dust and asteroids move around in space, but in different directions.
The effect happens when these space dust and particles are hit by light from the Sun. When the light rays hit these particles, it causes a tiny force which makes them move in circles around the Sun. This force isn't very strong, but it's enough to slowly change the direction the particles are travelling in, and helps them move around in space.
If the particles didn't have the Poynting–Robertson Effect, they would just travel in straight lines away from the Sun, and we wouldn't be able to see all the beauty of the solar system.
