Space junk is all the rubbish that humans have left in space. This includes old satellites（卫星）, used rocket（火箭）parts, and tiny pieces from crashes（碰撞）. In 2009, two satellites hit each other and created thousands of space junk pieces! Astronauts also lose small things in space sometimes. In 1965, astronaut Ed White lost a glove during a spacewalk. When we started exploring space, we started making space junk.
Space junk is a growing problem. It flies around Earth at about 20,000 km per hour! So even a small piece can damage a spacecraft（航天器）. There are over 36,000 big pieces and millions of smaller ones moving around our planet. More junk means more crashes and even more junk.
Scientists are thinking of ways to clean it up. All countries need to work together to keep space safe. After all, space is valuable for everyone. By working together, we can solve this problem and continue our exciting space journey.
