Earth is a dynamic, rocky planet approximately 12,700 kilometers in diameter, orbiting a stable star called the Sun. It has diverse landscapes, including continents, oceans, mountains, and forests, supporting a vast array of life forms. Earth’s atmosphere contains nitrogen and oxygen, enabling breathing and climate regulation. Its surface experiences weather patterns driven by solar energy, with a magnetic field protecting it from harmful solar radiation. As the only known planet with abundant surface water and complex ecosystems, Earth is vital for sustaining life and maintaining a delicate balance of ecological processes.
