Moons
Bodies that
orbit
planets
, ranging from the tiny to the gigantic. At least in
Earth's
solar system
, moons are a common phenomenon - of the nine
planets
, only
Mercury
and
Venus
are moonless.
The second largest moon in the
Solar System
(after Ganymede) is
Titan
, seen here with its parent
planet
Saturn
. Its thick orange clouds cover a body that has almost twice the mass of
Earth's
Moon
.
