Why is earth a planetary body?

Earth is considered a planetary body because it is a large, celestial object that orbits the Sun, is spherical in shape due to its own gravity, and has cleared its orbit of other debris. It exhibits characteristics typical of planets, such as a solid surface, an atmosphere, and geological activity. Additionally, Earth supports life, making it unique among known planetary bodies. These features are consistent with the definitions used by astronomers to categorize planets within our solar system.
