Our home. Mild, water-rich, and shielded by an active magnetic field.
Earth sits in the habitable zone where liquid water can exist. Our atmosphere is thick enough to shield us from cosmic radiation and trap just enough warmth for life, while thin enough to prevent runaway heating.
Verified science answered in plain, accessible language.
Earth maintains liquid water thanks to its goldilocks distance from the Sun, an active carbon cycle, and an atmosphere balanced with 78% Nitrogen and 21% Oxygen protected by a geomagnetic field.
The highest verified natural temperature is 56.7°C (134°F) in Death Valley, USA; the lowest is -89.2°C (-128.6°F) at Vostok Station, Antarctica.
Solar wind particles collide with Earth's magnetosphere and excite oxygen and nitrogen atoms in the upper atmosphere, emitting green, purple, and crimson photons.
The estimated average temperature on Earth is +15°C / +59°F.
A full day-night cycle on Earth lasts about 24 Earth hours.
Earth is 0 km (Home).
Earth's atmospheric pressure is 1.013 bar (1 atmosphere at sea level).
78% Nitrogen, 21% Oxygen, and water vapor clouds, creating stable atmospheric pressure.
From gentle coastal breezes to 300+ km/h hurricanes and tornadoes.
Rainstorms, blizzards, monsoons, hurricanes, and shimmering polar auroras.
