Our home world
Earth is the third planet from the Sun and the only known world to harbor life. Its unique combination of liquid water, a protective magnetic field, a breathable atmosphere, and moderate temperatures make it a haven for an extraordinary diversity of life forms. Earth's surface is 71% water, and its atmosphere is primarily nitrogen (78%) and oxygen (21%). The planet's axial tilt of 23.5 degrees gives rise to seasons, while the Moon stabilizes this tilt over long periods. Earth is approximately 4.54 billion years old.
