The earth is a planet. There are 9 planets. Gas and dust make the planets.
Earth is the third planet from the sun.
The earth goes around the sun once every 365 days. The earth moves 24 hours to make day and night. The earth's surface is always changing. Gravity holds everything on earth down so objects don't float out in space. If the sun was too far away from earth, the earth would get too cold and nothing could live on it.
