Facts about Neptune At 30,775 miles in diameter, Neptune is the

eighth and last planet of our solar system, now that Pluto has been demoted to planetoid status. It is about 2.7 billion miles away from the Sun, has a day lasting about 16 hours and orbits once every 165 years.

Named after the Roman god of the oceans because of its blue color, Neptune has no solid surface. Instead, its clouds of hydrogen, helium and methane swirl at up to 700 miles per hour around a core of liquid and rock.

Temperature

The planet's tilt of 28 degrees from the perpendicular produces seasonal temperature changes with cloud temperatures ranging from -240 degrees to -330 degrees Fahrenheit. A dark weather system was discovered in 1989 but had disappeared by 1994

Moons The planet has 13 known moons. The

largest is Triton at 1,350 miles in diameter, which has a thin atmosphere and at -391 degrees Fahrenheit, a colder surface than any in the solar system.

The surface is believed to be a mix of rock, and methane and nitrogen ice, with volcanoes spouting plumes of liquid nitrogen, methane and dust.

Triton (example the moon around the earth)

This moon is the only major one to orbit in a retrograde motion--that is, in a direction opposite to the rotation of the planet.
