A planet is a celestial body that orbits the Sun or another star and is not a satellite of another planet or moon. It is typically spherical in shape and is large enough to have cleared its orbit of other debris. There are eight recognized planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets vary in size, composition, and atmospheric conditions. Planets can be classified as either rocky or gas giants, depending on their composition. They also have different characteristics such as their distance from the Sun, rotational period, and number of moons. In addition to the eight planets, there are also dwarf planets and other smaller objects that orbit the Sun.
