Discover Earth and the celestial family it belongs to.
Earth is the third planet from the Sun and the only known world to support life. It's about 70% covered in water and has a rich atmosphere of nitrogen and oxygen. Earthβs magnetic field and ozone layer protect us from harmful solar radiation, and its diverse ecosystems make it uniquely vibrant in the solar system.
Our solar system consists of the Sun β a G-type main-sequence star β and everything bound to it by gravity: eight planets, their moons, dwarf planets like Pluto, and countless asteroids and comets.
