Our amazing solar system
Our solar system is home to many amazing objects. At its centre is the Sun, a huge star that provides light and heat to all the planets. Earth is our home planet and is special because it has water and life. It moves around the Sun in one year and spins to create day and night.
The Moon is Earth's closest neighbour in space. It travels around our planet and has a rocky surface with many craters. Astronauts have visited the Moon and done experiments there. Besides, there are other interesting planets like Mars, which is called the "red planet" because of its colour.
Scientists called astronauts work on space stations and use special equipment to study stars and planets. They help us learn more about our universe through their important research.
