Movement of the Earth
If you are traveling forwards in a train, the things around you outside seem to be moving backwards. The sun seems to rise in the east, move across the sky, and set in the west. In other words, the sun seems to travel round the earth. However, this is not really true. It is the earth that is turning on its own axis. The earth also travels round the sun on an unchanging path, known as an orbit. There are seven other planets of different sizes, which all travel round the sun. These are known as the solar system.
