A planet is a body in space that revolves around a star. There are nine planets in our solar system, and these nine planets travel around the sun. The names of the planets are Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune, and Pluto. Planets travel in orbits around their stars . All of the planets of the solar system revolve in elliptical orbits. In other words, their orbits are like large, flat circles. The time that it takes a planet to make one revolution around the sun is called its year. The Greek were the first people to recognize and give names to some of the planets. The word planet comes from a Greek word meaning wanderer. If a person wanders, this means that he goes from one place to another and does not have a home.
