IN THE VOID.

Earth is more than just a planet; it is a complex, living shield in the harshness of the solar system. Discover its unique place among its celestial siblings.
While Earth is only the fifth largest planet in the solar system, it is the only planet in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
Earth has a very hospitable temperature and mix of chemicals that have made life abundant here. Most notably, Earth is unique in that most of our planet is covered in liquid water, since the temperature allows liquid water to exist for extended periods of time. Earth's vast oceans provided a convenient place for life to begin about 3.8 billion years ago.

EARTH: THE UNIQUE ANOMALY

The Hydrosphere

Earth is the only known planet with stable liquid water on its surface, crucial for all life forms.

The Atmosphere

A perfect 21% oxygen mix protected by a magnetic field that shields us from solar radiation.

The Biosphere

Millions of species live in a self-sustaining cycle found nowhere else in the known universe.

Plate Tectonics

Active geology that recycles carbon, keeping the planetary climate stable over billions of years.

Science Fact

"If Earth were just a few percent closer or further from the Sun, its oceans would either boil away or freeze solid, ending its ability to support life."
