THE BLUE PLANET
Earth is the third planet from the Sun
and the largest of the four terrestrial
planets.
It is the only world currently known to
support life. Liquid water covers roughly
71% of its surface, while its atmosphere
is dominated by nitrogen and oxygen.
Earth has a strong magnetic field, an
active geological system and a large
natural satellite — the Moon.
Its atmosphere and oceans help regulate
the planet's climate and make Earth a
remarkably dynamic world.
LIQUID WATER
Earth is the only known planet with
stable bodies of liquid water covering
a large portion of its surface.
MAGNETIC FIELD
Earth's magnetic field helps shield
the atmosphere and surface from
charged particles from the Sun.
ACTIVE PLANET
Plate tectonics, volcanism and erosion
constantly reshape Earth's surface.
THE MOON
The Moon is Earth's only natural satellite.
It orbits our planet at an average distance
of about 384,400 km.
Its gravitational interaction with Earth
drives ocean tides and helps stabilize
Earth's axial tilt.
The Moon is also the only extraterrestrial
world where humans have walked.
DID YOU KNOW?
Earth and the Moon are actually
moving around a shared center of mass
called the barycenter.
