Neptune is the eighth planet from the sun, and the
outermost gas giant in our solar system. Interestingly
enough due to Pluto's eccentric orbit, Neptune is
sometimes the furthest planet from the Sun. Orbiting
so far from it the planet receives very little heat.
Its surface temperature is -218 degrees C. However,
the planet seems to have an internal source of heat.
Neptune's atmosphere has the highest wind speeds in
the solar system, up to 2000 km/h. The planet has
large, dark ovals on its surface which astronomers
believe are hurricane-like storms. Neptune is never
visible with the naked eye so your only chance to have
a good look at it is if you download this high-quality
Planet Neptune 3D screensaver.
