Earth, our home planet, is the only known world to support life. It is located in the "habitable zone" of our solar system, where temperatures are just right for liquid water to exist on the surface. Earth has a diameter of about 12,742 kilometers and is composed of a variety of landscapes, including oceans, mountains, forests, and deserts. The atmosphere is made up mostly of nitrogen and oxygen, providing the necessary conditions for life to thrive. Earth’s rotation on its axis gives us day and night, while its orbit around the Sun causes the seasons. With a vast diversity of ecosystems and a rich history, Earth remains a unique and precious planet in the cosmos.
